Definition of thesis

Did you know.

In high school, college, or graduate school, students often have to write a thesis on a topic in their major field of study. In many fields, a final thesis is the biggest challenge involved in getting a master's degree, and the same is true for students studying for a Ph.D. (a Ph.D. thesis is often called a dissertation ). But a thesis may also be an idea; so in the course of the paper the student may put forth several theses (notice the plural form) and attempt to prove them.

You may have heard the word thesis as a standalone term or as a component of academic writing called a thesis statement . Keep in mind that these are two very different things.

• A thesis statement is a very common component of an essay, particularly in the humanities. It usually comprises 1 or 2 sentences in the introduction of your essay , and should clearly and concisely summarize the central points of your academic essay .
• A thesis is a long-form piece of academic writing, often taking more than a full semester to complete. It is generally a degree requirement for Master’s programs, and is also sometimes required to complete a bachelor’s degree in liberal arts colleges.
• In the US, a dissertation is generally written as a final step toward obtaining a PhD.
• In other countries (particularly the UK), a dissertation is generally written at the bachelor’s or master’s level.

Prevent plagiarism. Run a free check.

The final structure of your thesis depends on a variety of components, such as:

• Your discipline
• Your theoretical approach

Humanities theses are often structured more like a longer-form essay . Just like in an essay, you build an argument to support a central thesis.

In both hard and social sciences, theses typically include an introduction , literature review , methodology section ,  results section , discussion section , and conclusion section . These are each presented in their own dedicated section or chapter. In some cases, you might want to add an appendix .

Thesis examples

We’ve compiled a short list of thesis examples to help you get started.

• Example thesis #1:   “Abolition, Africans, and Abstraction: the Influence of the ‘Noble Savage’ on British and French Antislavery Thought, 1787-1807” by Suchait Kahlon.
• Example thesis #2: “’A Starving Man Helping Another Starving Man’: UNRRA, India, and the Genesis of Global Relief, 1943-1947″ by Julian Saint Reiman.

The very first page of your thesis contains all necessary identifying information, including:

• Your full title
• Your full name
• Your department
• Your institution and degree program
• Your submission date.

Sometimes the title page also includes your student ID, the name of your supervisor, or the university’s logo. Check out your university’s guidelines if you’re not sure.

Read more about title pages

The acknowledgements section is usually optional. Its main point is to allow you to thank everyone who helped you in your thesis journey, such as supervisors, friends, or family. You can also choose to write a preface , but it’s typically one or the other, not both.

Read more about acknowledgements Read more about prefaces

An abstract is a short summary of your thesis. Usually a maximum of 300 words long, it’s should include brief descriptions of your research objectives , methods, results, and conclusions. Though it may seem short, it introduces your work to your audience, serving as a first impression of your thesis.

Read more about abstracts

A table of contents lists all of your sections, plus their corresponding page numbers and subheadings if you have them. This helps your reader seamlessly navigate your document.

Your table of contents should include all the major parts of your thesis. In particular, don’t forget the the appendices. If you used heading styles, it’s easy to generate an automatic table Microsoft Word.

While not mandatory, if you used a lot of tables and/or figures, it’s nice to include a list of them to help guide your reader. It’s also easy to generate one of these in Word: just use the “Insert Caption” feature.

Read more about lists of figures and tables

If you have used a lot of industry- or field-specific abbreviations in your thesis, you should include them in an alphabetized list of abbreviations . This way, your readers can easily look up any meanings they aren’t familiar with.

Relatedly, if you find yourself using a lot of very specialized or field-specific terms that may not be familiar to your reader, consider including a glossary . Alphabetize the terms you want to include with a brief definition.

An introduction sets up the topic, purpose, and relevance of your thesis, as well as expectations for your reader. This should:

• Ground your research topic , sharing any background information your reader may need
• Define the scope of your work
• Introduce any existing research on your topic, situating your work within a broader problem or debate
• State your research question(s)
• Outline (briefly) how the remainder of your work will proceed

In other words, your introduction should clearly and concisely show your reader the “what, why, and how” of your research.

Read more about introductions

A literature review helps you gain a robust understanding of any extant academic work on your topic, encompassing:

• Selecting relevant sources
• Determining the credibility of your sources
• Critically evaluating each of your sources
• Drawing connections between sources, including any themes, patterns, conflicts, or gaps

A literature review is not merely a summary of existing work. Rather, your literature review should ultimately lead to a clear justification for your own research, perhaps via:

• Addressing a gap in the literature
• Building on existing knowledge to draw new conclusions
• Exploring a new theoretical or methodological approach
• Introducing a new solution to an unresolved problem
• Definitively advocating for one side of a theoretical debate

Read more about literature reviews

Theoretical framework

Your literature review can often form the basis for your theoretical framework, but these are not the same thing. A theoretical framework defines and analyzes the concepts and theories that your research hinges on.

Read more about theoretical frameworks

Your methodology chapter shows your reader how you conducted your research. It should be written clearly and methodically, easily allowing your reader to critically assess the credibility of your argument. Furthermore, your methods section should convince your reader that your method was the best way to answer your research question.

A methodology section should generally include:

• Your overall approach ( quantitative vs. qualitative )
• Your research methods (e.g., a longitudinal study )
• Your data collection methods (e.g., interviews or a controlled experiment
• Any tools or materials you used (e.g., computer software)
• The data analysis methods you chose (e.g., statistical analysis , discourse analysis )
• A strong, but not defensive justification of your methods

Read more about methodology sections

Your results section should highlight what your methodology discovered. These two sections work in tandem, but shouldn’t repeat each other. While your results section can include hypotheses or themes, don’t include any speculation or new arguments here.

Your results section should:

• State each (relevant) result with any (relevant) descriptive statistics (e.g., mean , standard deviation ) and inferential statistics (e.g., test statistics , p values )
• Explain how each result relates to the research question
• Determine whether the hypothesis was supported

Additional data (like raw numbers or interview transcripts ) can be included as an appendix . You can include tables and figures, but only if they help the reader better understand your results.

Read more about results sections

Your discussion section is where you can interpret your results in detail. Did they meet your expectations? How well do they fit within the framework that you built? You can refer back to any relevant source material to situate your results within your field, but leave most of that analysis in your literature review.

For any unexpected results, offer explanations or alternative interpretations of your data.

Read more about discussion sections

Your thesis conclusion should concisely answer your main research question. It should leave your reader with an ultra-clear understanding of your central argument, and emphasize what your research specifically has contributed to your field.

Why does your research matter? What recommendations for future research do you have? Lastly, wrap up your work with any concluding remarks.

Read more about conclusions

In order to avoid plagiarism , don’t forget to include a full reference list at the end of your thesis, citing the sources that you used. Choose one citation style and follow it consistently throughout your thesis, taking note of the formatting requirements of each style.

Which style you choose is often set by your department or your field, but common styles include MLA , Chicago , and APA.

Create APA citations Create MLA citations

In order to stay clear and concise, your thesis should include the most essential information needed to answer your research question. However, chances are you have many contributing documents, like interview transcripts or survey questions . These can be added as appendices , to save space in the main body.

Read more about appendices

Once you’re done writing, the next part of your editing process begins. Leave plenty of time for proofreading and editing prior to submission. Nothing looks worse than grammar mistakes or sloppy spelling errors!

Consider using a professional thesis editing service or grammar checker to make sure your final project is perfect.

Once you’ve submitted your final product, it’s common practice to have a thesis defense, an oral component of your finished work. This is scheduled by your advisor or committee, and usually entails a presentation and Q&A session.

After your defense , your committee will meet to determine if you deserve any departmental honors or accolades. However, keep in mind that defenses are usually just a formality. If there are any serious issues with your work, these should be resolved with your advisor way before a defense.

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

If you only used a few abbreviations in your thesis or dissertation , you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimizing confusion about abbreviations unfamiliar to your reader.

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organize your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation , such as:

• Your anticipated title
• Your abstract
• Your chapters (sometimes subdivided into further topics like literature review , research methods , avenues for future research, etc.)

A thesis is typically written by students finishing up a bachelor’s or Master’s degree. Some educational institutions, particularly in the liberal arts, have mandatory theses, but they are often not mandatory to graduate from bachelor’s degrees. It is more common for a thesis to be a graduation requirement from a Master’s degree.

Even if not mandatory, you may want to consider writing a thesis if you:

• Plan to attend graduate school soon
• Have a particular topic you’d like to study more in-depth
• Are considering a career in research
• Would like a capstone experience to tie up your academic experience

The Thesis Sentence

The thesis sentence is arguably the most important sentence in an academic paper. Without a good, clear thesis that presents an intriguing arguable point, a paper risks becoming unfocused, aimless, not worth the reader's time.

The Challenge of the Thesis Sentence

Because the thesis sentence is the most important sentence of a paper, it is also the most difficult to write. Readers expect a great deal of a thesis sentence: they want it to powerfully and clearly indicate what the writer is going to say, why she is going to say it, and even how it is that she is going to go about getting it said. In other words, the job of the thesis sentence is to organize, predict, control, and define the paper's argument.

In many cases, a thesis sentence will not only present the paper's argument, it will also point to and direct the course that the argument is going to take. In other words, it may also include an "essay map" - i.e., phrases or clauses that map out for the reader (and the writer) the argument that is to come. In some cases, then, the thesis sentence not only promises an argument, it promises the structure of that argument as well.

The promises that a thesis sentence makes to a reader are important ones and must be kept. It's helpful sometimes to explain the thesis as a kind of contract between reader and writer: if this contract is broken, the reader will feel frustrated and betrayed. Accordingly, the writer must be very careful in the development of the thesis.

Working on the Thesis Sentence

Chances are if you've had trouble following or deciphering the argument of a paper, there's a problem with the thesis. If a tutor's first response to a paper is that he doesn't know what the paper is about, then the thesis sentence is either absent from the paper, or it's hiding. The first thing you might wish to do is to ask the writer what his thesis is. He may point to a particular sentence that he thinks is his thesis, giving you a very good place to start.

Let's say that you've read a paper in which you've encountered this thesis:

Although heterosexuality has long been regarded as the only natural expression of sexuality, this view has been recently and strongly challenged by the gay rights movement.

What's wrong with this sentence? Many things, the most troublesome of which is that it argues nothing. Who is going to deny that the heteronormative view has been challenged by the gay rights movement? At this point, you need to ask the writer some questions. In what specific ways has the gay rights movement challenged heterosexuality? Do these ways seem reasonable to the writer? Why or why not? What argument does he intend to make about this topic? Why does he want to make it? To whom does he want to make it?

After giving the writer some time to think about and talk about these questions, you'll probably want to bring up another problem that is certain to arise out of a thesis like this one: the matter of structure. Any paper that follows a thesis like this one is likely to ramble. How can the reader figure out what all the supporting paragraphs are doing when the argument itself is so ill-defined? You'll want to show the writer that a strong thesis suggests - even helps to create - strong topic sentences. (More on this when we consider matters of structure, below).

But before we move on to other matters, let's consider the problem of this thesis from another angle: its style. We can see without difficulty that the sentence presents us with at least two stylistic problems: 1) this thesis, which should be the most powerful sentence of the paper, employs the passive voice, and 2) the introductory clause functions as a dangling modifier (who regards heterosexuality as the only natural way to express sexuality?).

Both stylistic problems point to something at work in the sentence: the writer obliterates the actors - heterosexuals and homosexuals alike - by using the dangling modifier and the passive voice. Why does he do that? Is he avoiding naming the actors in these sentences because he's not comfortable with the positions they take? Is he unable to declare himself because he feels paralyzed by the sense that he must write a paper that is politically correct? Or does he obliterate the actors with the passive voice because he himself wishes to remain passive on this topic?

These are questions to pose to the writer, though they must be posed gently. In fact, you might gently pose these questions via a discussion of style. For instance, you might also suggest that the writer rewrite the sentence in the active voice:

Although our society has long regarded heterosexuality as the only natural expression of sexuality, members of the gay rights movement have challenged this view strongly.

This active construction helps us to see clearly what's missing:

Although our society has long regarded heterosexuality as the only natural expression of sexuality, members of the gay rights movement have challenged this view strongly, arguing XYZ.

This more active construction also makes it clear that merely enumerating the points the author wants to make is not the same thing as creating an argument. The writer should now be able to see that he needs to go one step further - he needs to reveal his own position on the gay rights movement. The rest of the paper will develop this position.

In short, there are many ways to begin work on a writer's thesis sentences. Almost all of them will lead you to other matters important to the paper's success: its structure, its language, its style. Try to make any conversation you have about thesis sentences point to other problems with the writing. Not only is this strategy efficient, but it also encourages a writer to see how important a thesis is to the overall success of his essay.

Talking Your Way to a Workable Thesis

For the sake of making (we hope) a somewhat humorous illustration of the matter at hand, we offer the following scenario, which shows how tutor and tutee can talk their way to a workable thesis - and, indeed, to a good essay. So sit back, and enjoy this "break" in your training.

Imagine (though it is indeed quite a stretch) that a freshman composition teacher has the audacity to assign a paper on cats (the animals, not the play). The students may write any kind of paper they like - narration, description, compare/contrast, etc. - as long as their essays contain a thesis (that is, that they argue some point) concerning cats. A writer comes to you for help in developing her thesis. You read the assignment, and then you tell the writer that she first must choose the kind of paper she would like to do. She decides to do a narrative because she thinks she has more freedom in the narrative form. Then you ask her what she has to say about cats. "I don't like them," is her reply.

"OK," you say, "that's a start. Why don't you like them?" The writer has lots of reasons: they smell, they're aloof, they shed, they keep you up nights when they're in heat, they're very middle class, they steal food off of the table, they don't get along with dogs (the writer loves dogs), and on, and on. After brainstorming for a while, you tell the writer to choose a few points on which she'd like to focus - preferably those points that she feels strongly about or those which seem unusual. She picks three: cats smell, they steal food, and they are middle class. She offers her thesis: "I don't like cats because they are smelly, thieving, and middle class."

"O.K.," you say, "It's not a very sophisticated thesis but we can use it for now. After all, it defines your stance, it controls your subject, it organizes your argument, and it predicts your strategy - all the things that a thesis ought to do. Now let's consider how to develop the thesis, point by point."

You begin to ask questions about cats and their smell. "What do they smell like?" you say. The writer thinks awhile, and then says, "They smell like dirty gym shorts, like old hamburgers, like my eighth-grade math teacher's breath." The writer laughs, particularly fond of the final simile. Then she adds, "My boyfriend has a cat. A Tom. When he moved into his first apartment, that cat sprayed all over the place, you know, marking his territory. The place stunk so bad that I couldn't even go there for a week. Can you imagine? Your boyfriend gets his first apartment, and you can't even go in the place for a week?"

The writer has sparked your imagination; you think that she can spark her teacher's imagination as well. "Why don't you do your narrative about your boyfriend's cat? You could tell the story - or you could make up a story - about going over there for dinner, hoping for a romantic evening, and being put off by the cat." The writer likes this idea and goes off to write her draft. She returns with the following story about her boyfriend and his cat.

She was hoping for a romantic dinner; he was making her favorite meal. She could smell the T-bone and the apple pie before she even got to his door. But when she opened the door, her appetite was obliterated: the smell of cat spray smelled worse than her eighth-grade math teacher's breath. Of course, because she remained hopeful for a romantic evening, she put on her best face, tried not to grimace, and gave her boyfriend the flowers she'd picked up on the way. They chat; everything is going fine; he goes to the kitchen to check on dinner; she hears his shriek. The cat has stolen all of the food! Upon searching, they find the cat under the sofa, not only with their dinner, but with the writer's wallet, her favorite picture of her mom torn in half, her new leather jacket now full of cat hairs. This cat not only stinks, he's a thief as well. Still, the evening need not be a total waste. They order pizza, have some wine. She and her man talk; their moods improve, and she decides that it might be a nice time to kiss. She pulls the old yawn trick to get her arm around him, and just as she's ready to kiss him the cat jumps into his lap. "Oh, Pookie, Pookie, Pookie," her boyfriend says, giving himself over to the purring cat. "Damn lap cat," the writer says to herself, and leaves it at that. She has written a paper illustrating that cats are smelly, thieving, and middle class. She has fulfilled her thesis.

Now, you like this paper. It's got a great voice, and it's got humor. You feel, however, that the writer should refine the thesis. It has served the writer well in helping her to organize, control, predict, and define her essay; however, she needs now to consider how to choose words and a tone which will hook the reader and reel him in. You explain to the writer that her thesis can be humorous, that she can feel free to be extreme, because a funny, exaggerated thesis would suit this funny, exaggerated paper.

After some doodling and some dialogue, the writer comes up with the following thesis: "All cats should be exterminated because they are the stinking, kleptomaniacal darlings of the bourgeoisie." You laugh; you like it. Moreover, the thesis has given the writer an ending for her essay: she exterminates the cat in her boyfriend's microwave, convinces him to get a goldfish instead, and the two of them live happily ever after. The writer is happy. The tutor is happy. The paper works.

While you will likely not encounter a "cat" assignment at Dartmouth, this sort of experience with writing a thesis is a common one. Even when papers are more sophisticated than this one - even when the subject is Hitler's rise to power, or Freud's treatment of taboo - writers will often write a working thesis, one that guides them through the writing process. Then they will return to the thesis, sometimes several times before their paper is finished, revising it to better fit their paper's increasingly refined argument and tone.

Polishing the Thesis Sentence

Look at the sentence's structure. Is the main idea of the paper placed appropriately in the main clause? If there are parallel points made in the paper, does the thesis sentence signal this to the reader via some parallel structure? If the paper makes an interesting but necessary aside, is that aside predicted - perhaps in a parenthetical element? Remember: the structure of the thesis sentence also signals much to the reader about the structure of the argument. Be sure that the thesis reflects, reliably, what the paper itself is going to say.

As to the style of the sentence: hold the thesis sentence to the highest stylistic standards. Help a writer to make sure that it is as clear and concise as it can be, and that its language and phrasing reflect confidence, eloquence, and grace.

Teaching the Thesis Sentence

Most writing teachers agree that the thesis occupies a very important position, both in our student papers and in our teaching. We also agree that students tend to "rush" the thesis, and that the dominance (or even the presence) of a thesis (especially a premature thesis) can get in the way of a good paper. Accordingly, most writing instructors have a repertoire of methods to help students find a thesis that will focus and guide an interesting and persuasive academic paper. We offer some of those methods here, with the observation that these instructors in fact teach the thesis in multiple ways in their classrooms.

Here, then, are some things to try as you get students to write better theses:

• Respect their opinions (even if you don't agree with them), and show them how to harvest these opinions for academic purposes.
• Ask students to look for parts and patterns in a text and to develop their analysis from these patterns.
• Move your students back and forth, from the particular to the general, until they find the right "fit" between their particular observations and the Big Idea of the text.
• Ask them to develop an "umbrella idea" that synthesizes seemingly disparate observations.
• Instruct your students to look for hidden assumptions, both in the texts they're writing about and in their own work. Present the question: What needs to be true about the world for this claim to be true?
• Help your students expand their thesis sentences by introducing a counter-claim or complicating evidence. Then work with them to consider how to balance these claims in their paper/thesis.
• Debunk the thesis—and then debunk the debunking. Encourage students to keep looking for evidence that challenges their thesis (and not just evidence that supports it).
• Ask students to draw their papers. This frees them from thinking linearly and helps them to consider possibilities that might not have appeared to them otherwise.
• Warn students against common thesis problems, including the One-Size-Fits-All Thesis and the Laundry List Thesis. Encourage them to integrate their ideas rather than list them.
• Finally, remind students that there is no formula for a good thesis: form is dictated by idea, and not vice versa. Understanding the principles of style will help you and your students to create a sentence whose structure reflects the structure of the argument.

Shelby Grantham: Thesis Writing from the Solar Plexus

Professor Grantham's advice, in a nutshell, is "Find a topic that matters to you, and then figure out why it matters to you." This may sound like an obvious place to start, but it's not. Students are generally looking not for topics that interest them, but topics that interest the teacher—not understanding that we find it exciting to discover their arguments, their points of view.

Students often have very good instincts about paper topics, but they don't know what to do with their ideas. The first thing that they are likely to do is to take their good instinct for a paper topic and try to abstract it. Before attempting any abstractions, students should first consider why this topic, in particular, interests them. Professor Grantham has her students freewrite on a topic, asking them to explore their own feelings, experiences, and ideas. Students are not to worry about grammar, nor are they asked to consider structure. Rather, they are asked to respond as honestly and as fully as they can.

The instructor will then use this freewrite as the starting point for a conference about the paper that the student really wants to write. In that conference, Professor Grantham and the student "mine" the freewriting exercise for possible paper topics—not theses, but topics.

Once a topic is selected, students must consider it carefully before proposing a thesis. Professor Grantham will eventually ask students to do the necessary textual analysis or research, but before she does she asks students to unpack their own beliefs on the topic. Professor Grantham proceeds on the assumption that our students have a vast amount of information and opinion stored within, and that they have warrant for the beliefs they carry with them. She asks them to determine where they got the evidence for their beliefs—to trace the source of the belief to family members, friends, television. Once they've found the roots of their beliefs, they are then ready to decide whether they want to hold firm or change their minds.

Finally, students are ready (tentatively) to posit a thesis.

John Donaghy: Finding Patterns, Solving Problems

Professor Donaghy's method is founded on the understanding that analysis is a complicated process that requires us to break down a text (event, object, or phenomenon) into parts, discovering patterns among the parts, and coming up with a theory for why these patterns exist. Donaghy believes that students are initially afraid of analysis, and that their initial attempts at it are either overly simple, or disjointed and disorganized. He's puzzled by this fear, as we are analyzing all the time: life presents us with data that we are continually sorting by finding patterns, creating categories, and making meaning. Analysis is requisite for something as simple as crossing the street. Students can be encouraged to see that they already possess analytical skills that can be transferred to writing papers.

Professor Donaghy suggests three steps regarding a simple analysis of the following Gary Snyder poem, "Pine tree tops:"

In the blue night frost haze, the sky glows with the moon pine tree tops bend snow-blue, fade into sky, frost, starlight. The creak of boots. Rabbit tracks, deer tracks, what do we know.

First, when analyzing, students need to be conscious of examining parts of a text, looking for patterns (or repeating elements). In a short poem, students can make a number of simple observations, including:

• Number of words (34)
• Number of syllables in words (mostly single syllable)
• Parts of speech: mostly nouns; adjectives are scarce; surprisingly few verbs

Second, students need to try to determine how these parts and patterns are speaking to each other. Do these parts and patterns illustrate a similarity? Draw a contrast? Create an emphasis? Together form a new observation or idea? In terms of the poem:

• Nouns: so many nouns emphasizes the "thing-ness" of the poem
• Adjectives: very few; one (blue) is attached to a noun
• Verbs: the verbs (glows, bend, fade) are gentle, yielding verbs

Finally, students can put forward a proposition. For instance: Snyder builds his poem on nouns to give power to the "things" in his scene. OR Snyder chooses verbs that seem to yield to the nouns in order to tell us how to behave in the presence of nature. This proposition, with some tweaking, can become a working thesis.

Karen Gocsik: Finding the Umbrella Idea

Finding the "umbrella idea" requires that students move back and forth between a text's particularities and its big ideas in order to find a suitable "fit" between the two that the students can write about. This fit is summed up in the "umbrella idea," or the big idea that all of their observations can stand under.

Some students begin with a very specific observation about a text—for instance, that on page 264 of Milan Kundera'sImmortality, the heroine of his novel declares that her father was her only love. This observation can't yield a paper. So what does the student do? She generalizes the issue. In other words, she looks not at the individual father-daughter relationship but considers other father-daughter relationships in the novel. But this observation won't yield a paper, either. The student must think in particulars once again, comparing the relationships to find interesting patterns. What she comes up with is that in one relationship, the daughter looks to the father for guidance; in the other she sees that it's quite the opposite: the father believes that his daughter has wisdom and seeks her counsel. Again, still not much going on. It's time to generalize to the novel's big ideas—which include an attack on modernism and a nostalgia for the traditions of Europe. Interestingly, the father daughter relationships can be linked, via textual evidence, to these ideas. The student has discovered a "fit" between the big ideas and her particular observations that can yield a paper.

The key to success in this method rests in four processes:

• Students must move fluidly back and forth between the text and their abstractions/generalizations, ready to adjust their ideas to the new evidence and new abstractions that they encounter.
• Students must sketch their ideas. Drawing their ideas helps students pull their thinking out of linear, two-dimensional modes, enabling them to see multiple possibilities for their essays.
• Students must seek an umbrella idea, under which their ideas can stand. To get to this umbrella idea, they need not only to analyze but to synthesize: they need to bring disparate ideas together, to see if they fit.
• They further need to create this synthesis by playing with language, creating an umbrella sentence that can embrace their ideas. This requires that students write and revise their thesis sentence several times as they write their paper. It also requires that students have a basic understanding of the principles of style, so that they can understand how to place their ideas in appropriate clauses, create the proper emphasis, and so on.

Sara Biggs Chaney: Evolving the Thesis by Unpacking the Assumptions & Making Counter-Claims

Professor Chaney's method asks students to arrive at a thesis by examining their assumptions. She begins her instruction by introducing the student to the enthymeme. Like the syllogism (All men are mortal; Socrates is a man; therefore, Socrates is mortal), the enthymeme has three parts: the major premise, the minor premise, and the conclusion. The difference is that in the case of the syllogism the major premise is based on fact (All men are mortal), while in the enthymeme it's based on a commonly held belief (cheating is unethical, smoking around children is a danger to their health, etc.). As Professor Chaney notes, in many cases the enthymeme is presented with the major premise left unstated: She smokes around her daughter; she endangers her daughter's health. Professor Chaney illustrates the importance in finding the "missing" major premise, arguing that unpacking an argument's unstated assumptions can help students to better analyze the texts they're writing about, and to create better texts of their own.

The key question to ask is: What must be true about the world in order for this statement to be true? Students are asked to put forth all hidden assumptions, large and small. This forces the students to dig beneath the surface of the text, to explore the structure and the nuance of the argument. In the process, ideas for a thesis will present themselves.

Once the students have drafted a thesis, Professor Chaney has a strategy (borrowed from David Rossenwasser and Jill Stephen's Writing Analytically) for evolving the thesis by putting forward counter-claims. She has found Rossenwasser and Stephen's types of weak thesis statements—"Procrustes' Bed" and "The Laundry List"—useful in diagnosing logic problems in student writing. Students tend either to force a diversity of evidence to fit an overly rigid claim, or to present their claim in the form of a list, with few connections between the points. To evolve the thesis, Professor Chaney requires students to begin with their basic claim and then to methodically increase the complexity of that claim through the introduction of complicating evidence. This new evidence forces students to redefine their initial claims and to determine how the counter-claim might or might not be accommodated by their thesis.

For instance, a student may have written the following thesis: "Reported cases of autism in children have increased by almost 200% in the last twenty years because autism has been redefined to include less severe forms of the disorder." Professor Chaney presents them with this complicating evidence: "Some research also suggests that autism may be linked to mercury exposure in childhood vaccines." Students may weigh the evidence to see which has more merit; they might expand their thesis to point to two reasons for rising autism; they might acknowledge the truth in both statements but want to subordinate one argument to the other; they might point out a causal relationship between the two sentences (i.e., has the frequent levels of mercury exposures led to a new definition of autism in the DSM-IV, which in turn has increased the numbers of reported cases of autism?). Using any of these methods, students will have improved their thesis sentences.

Tom Cormen: Debunking (and Re-Debunking) the Thesis

Professor Cormen also recognizes that students are quick to "rush to thesis," and so he created an exercise to show students how additional information (research) can flesh out a thesis sentence. Professor Cormen presents students with a short poem, "Baseball's Sad Lexicon," written in 1908 by Franklin P. Adams, for the New York  Globe . The poem laments how often it seemed that the Chicago Cubs' infield, with Joe Tinker, Johnny Evers, and Frank Chance, turned double plays to stifle potential rallies by the New York Giants:

These are the saddest of possible words,  Tinker-to-Evers-to-Chance.  Trio of Bear Cubs, fleeter than birds,  Tinker-to-Evers-to-Chance.  Ruthlessly pricking our gonfalon bubble,  Making a Giant hit into a double,  Words that are weighty with nothing but trouble,  Tinker-to-Evers-to-Chance.

Professor Cormen points out to his students that Tinker, Evers, and Chance are all in the Baseball Hall of Fame. They must have formed one of the greatest double-play combinations ever. Or did they? To debunk the myth of Tinker-to-Evers-to-Chance, Professor Cormen gives his students another essay, written in 1954 by Warren Brown, called "Don't Believe Everything You Read." This essay challenges the Tinker-to-Evers-to-Chance mystique by doing a bit of investigating uncovering that, at the height of their careers (1906 - 1909), the Tinker-to-Evers-to-Chance combination turned only 29 double plays. By comparison, a second baseman with the Detroit Tigers participated in 150 double plays in 1950 alone, and a shortstop with the Cleveland Indians figured in 134 double plays in 1944. By demonstrating that players a few decades later were turning many times the double plays in one season that Tinker, Evers, and Chance were turning in four seasons, clearly the writer of this essay has debunked the legend of Tinker-to-Evers-to-Chance.

Or has he? Professor Cormen asks students to consider the differences between baseball in 1908 and 1950. First, he asks them to consider the conditions of baseball fields in 1908: the fields were pocked and rocky, far from the groomed surfaces that we see today or were the norm by 1950. Second, he asks them to consider the gloves: not the cestas we see on players' hands today, or even the webbed gloves that players wore by the 1940s, but more like the winter gloves that we wear today, without the insulation. Finally, he asks students to consider the ball: it was neither perfectly round (balls were not as hard before the 1920s, and when a batted ball went into the stands, it was thrown back onto the field and continued to be used) nor perfectly white (before the spitball was outlawed in 1920, balls were stained brown with tobacco juice, making them hard to see). Tinker, Evers and Chance were playing on a field like a parking lot, with gloves like a motorman's mitt, and with a ball that more resembled a mini-football than what we think of as today's baseballs. How could anyone expect them to turn 150 double plays per year? Clearly, with this additional evidence, students are moved to compose a more complex thesis.

The moral of the story: as students engage in research, they will encounter evidence that will debunk (or at least challenge) their ideas. Encourage this research, and support students as they work toward better thesis sentences.

PhD Theses Grammar – Nouns & Words Both, Either, Neither, Nor & Only

Posted by Rene Tetzner | Oct 30, 2021 | PhD Success | 0 |

5.4.3 Nouns and Agreement

The use of most English nouns is relatively straightforward, but spelling and word choice can sometimes be an issue if English is not your native language. It is usually quite easy to deal with such problems through careful and critical proofreading, especially with the assistance of the spell-checking function of your word-processing program, which in most cases will highlight obvious errors (though it should not be trusted to discover them all). If a word is underlined or otherwise highlighted by the program, check the spelling and correct it if necessary; if spelling is not the problem, it is likely that you have chosen the wrong or an inappropriate word (perhaps you used ‘content’ for ‘context,’ for example, ‘implementation’ for ‘intervention’ and so on), in which case you will need to use a dictionary or perhaps a thesaurus to find the correct or a more appropriate word. Watch for nouns that are too vague to express your exact meaning to all readers: ‘in this context,’ ‘in our area’ and ‘in local universities’ are classic examples of instances in which you and your thesis committee will know what you are talking about, but other readers (especially those from other contexts and areas) cannot unless the context or area you are working in or the location of those universities is specified wherever necessary for absolute clarity (specific language is also best for dates: see Section 6.4.4). Conversely, your language should not be so specific to one country or region that its meaning will not be fully understood by international readers: currency and educational systems are good examples of topics for which you should provide not only specific information relevant to the original locality, but also careful enough explanations of the specifics to make them clear to readers who are not familiar with that locality and its culture.

Agreement should always be maintained between nouns and the verbs used with them, which in most cases is easily established: singular nouns should be used with the singular forms of verbs (‘the doctoral candidate investigates,’ ‘the brush untangles’ and ‘the child plays’) and plural nouns with the plural forms of verbs (‘the doctoral candidates investigate,’ ‘the brushes untangle’ and ‘the children play’). If you want your language to suggest the possibility of both singular and plural situations simultaneously, for most nouns you can enclose the ‘s’ or ‘es’ of the plural form in parentheses – ‘the methodology chapter(s)’ – in which case the verb form should be governed by the singular noun because the plural is technically parenthetical: for example, ‘the methodology chapter(s) describes the research methods used in the thesis.’ Another (and often preferable) solution is to word the text in such a way that the verb works for both the singular and plural forms of the noun: ‘the methodology chapter(s) should describe the research methods used in the thesis.’ With plural nouns formed through the addition of endings other that ‘s’ or ‘es,’ the same strategy can be used – ‘the child(ren) will be going to a party this afternoon’ – but with nouns that change their stems to form the plural (such as ‘man’ that becomes ‘men’ and ‘woman’ that becomes ‘women’), effective constructions can be complicated and confusing for readers, and are generally best avoided.

There are certain nouns in the English language that present special challenges when it comes to agreement. Plural nouns that seem like singular nouns (‘data,’ ‘media,’ ‘criteria’ etc.), for instance, should take a plural verb (‘the criteria required were,’ not ‘the criteria required was’), although ‘data’ can, alternatively, be used as a singular noun (‘the data were’ or ‘the data was’). This is to say that ‘data’ can be treated as a collective or group noun instead of as a normal plural noun, in which case the important point is to ensure that the noun is treated as a singular whenever it is used in a document. With collective nouns in general, it is essential that each noun is consistently treated as either a singular or a plural, ideally throughout a thesis and certainly within a single sentence, but this can be rather tricky because such nouns tend to be used as both singular and plural in casual conversation, so there is a tendency to be inconsistent: for example, in ‘The society was founded in 1995; since then, they have grown rapidly,’ ‘they have’ in the second part of the sentence should actually be ‘it has’ to agree with the singular ‘society’ and its verb ‘was’ in the first part. Also complicated is the fact that the decision to use a singular or plural verb with a collective noun can depend on whether the noun refers to the group as a unit (singular) or to its members as individuals (plural), and also on whether British or American English is used: in American English, when the group is considered as a unit, a singular verb is usually used (our hockey team is playing very poorly this year), but in British English, collective nouns tend to use plural verbs (our hockey team are playing very poorly this year). The collective nouns ‘couple’ and ‘pair’ are usually used as plurals when they refer to people – ‘The couple ride their bicycles to work’ – but collective nouns of quantity such as ‘number,’ ‘percentage’ and ‘proportion’ tend to take a singular verb when a definite article precedes the noun and a plural verb when an indefinite article precedes the noun (‘The proportion of customers with home phones is decreasing,’ but ‘A large proportion of customers are giving up their home phones in favour of mobile phones’).

5.4.4 Both, Either, Neither, Nor and Only

Certain other words, phrases and constructions can cause particular problems when constructing sentences, especially for authors whose native language is not English. ‘Both’ takes a plural verb (e.g., ‘both a pool and a water slide were added to the playground’), whereas ‘either’ and ‘neither’ take a singular verb (either a pool or a water slide is being added to the playground), and so does a ‘neither . . . nor’ construction (neither a pool nor a waterslide was added to the playground). Please note that ‘or’ should not be used instead of ‘nor’ in a ‘neither . . . nor’ construction.’ ‘Neither,’ ‘either’ and ‘both’ should be correctly positioned in a sentence to achieve balance and avoid repetition, so the phrasing should be ‘that affect neither him nor her,’ not ‘that neither affect him nor her,’ and ‘that affect both him and her,’ not ‘that both affect him and her.’ ‘Only’ can be placed where it sounds best in a sentence unless there is a possibility of ambiguity or confusion, in which case it should be carefully positioned to clarify the meaning: for example, ‘vegetable gardens only watered on Sundays’ could mean ‘only vegetable gardens are watered on Sundays’ or ‘vegetable gardens are watered on Sundays only’ or ‘vegetable gardens are watered, but not weeded, on Sundays’ (examples adapted from Butcher et al., 2006, p.164). It is therefore wise to consider all the placement and semantic options as you are writing such sentences and choose the one that most effectively expresses your intentions. ‘Only’ can also be problematic when used not to mean ‘exclusively,’ but to refer to a small number or percentage: ‘just 39%’ or ‘as small as 39%’ is more accurate than and preferable to ‘only 39%.’

5.4.5 Beginning Sentences Correctly and Avoiding Dangling Participles

The wording at the beginning of sentences should be both precise and complete in formal scholarly prose, and certain elements should not be used in that position. Numerals, for instance, should be avoided, so any number at the beginning of a sentence should be written out in words unless writing it out would be cumbersome (e.g., ‘237,482’ would be very unwieldy if written as words), in which case the sentence should be reworded to avoid using the number at its beginning (for information on formatting numbers, see Section 6.4 below). Certain abbreviations should also be avoided at the beginning of sentences, although acronyms and initialisms are usually acceptable (see Section 6.3.8 below). As a general rule, sentences should not begin with conjunctions such as ‘and,’ ‘or,’ ‘but’ and ‘so,’ although the occasional lapse in this regard, even in formal writing, is tolerated in most cases as long as the sentence does not begin a paragraph, the meaning is clear and the rhythm of the prose is effective. A sentence and especially a paragraph should not normally start with a pronoun such as ‘this,’ ‘that’ or ‘they’ even if the antecedent is clear from what has gone before, but particularly if the antecedent is at all ambiguous. Instead, the subject should be clearly stated as a noun or noun phrase to avoid confusion, but the pronoun ‘I’ (as well as ‘we’ in texts with more than one author) is acceptable at the beginning of a sentence or paragraph because there can be no doubt, if the pronoun is used only when it should be, about the meaning. Keep in mind that when a descriptive phrase is used at the beginning of a sentence, it applies to everything that follows until the subject changes or is restated: in the sentence ‘In 1879 he painted his first watercolour and began to work with oils in 1886,’ for instance, the date 1879 applies incorrectly to ‘began’ as well as correctly to ‘painted,’ so rewording is necessary: either ‘He painted his first watercolour in 1879 and began to work with oils in 1886’ or ‘In 1879 he painted his first watercolour, and in 1886 he began to work with oils’ would work.

Dangling participles are often problematic at the beginning of sentences, though they can turn up anywhere in a sentence. A dangling participle occurs when a participle or participial phrase is followed by a word other than the subject it modifies, as it is in ‘Plunging to enormous depths, we marvelled at the canyon’ and ‘Having found the right food at last, the diabetic dog was fed.’ It is clear to a thinking reader familiar with English that the ‘canyon’ plunges ‘to enormous depths’ and the person feeding the dog is the one who ‘found the right food,’ but the sentences do not actually say these things: they say that ‘we’ plunge ‘to enormous depths’ and ‘the diabetic dog’ was the one who ‘found the right food’ because those are the subjects that appear immediately after the participial phrases. Such sentences should be reworded so that their syntax reflects the realities reported: ‘We marvelled at the canyon that plunged to enormous depths’ and ‘Having found the right food at last, he fed the diabetic dog.’ Other kinds of dependent clauses that frequently appear at the beginning of sentences can present problems as well, particularly when they are mistakenly used as independent clauses or full sentences. Although a dependent clause contains a subject and a verb (as the opening clause of this sentence does), it does not express a complete thought; instead, it often begins with a dependent marker word (such as ‘after,’ ‘when,’ ‘if,’ ‘because’ and ‘although’) that leaves the reader waiting for the rest of the thought: ‘After he had drafted his thesis’ and ‘Because she is afraid of fireworks’ are good examples. For this reason, a dependent clause cannot be a complete sentence, but should be either followed by a comma and an independent clause that does complete the thought, or preceded by an independent clause and (if necessary) a comma: ‘After he had drafted his thesis, he had it checked by a professional proofreader’ or ‘We left our dog at home because she is afraid of fireworks.’

Why PhD Success?

To Graduate Successfully

This article is part of a book called "PhD Success" which focuses on the writing process of a phd thesis, with its aim being to provide sound practices and principles for reporting and formatting in text the methods, results and discussion of even the most innovative and unique research in ways that are clear, correct, professional and persuasive.

The assumption of the book is that the doctoral candidate reading it is both eager to write and more than capable of doing so, but nonetheless requires information and guidance on exactly what he or she should be writing and how best to approach the task. The basic components of a doctoral thesis are outlined and described, as are the elements of complete and accurate scholarly references, and detailed descriptions of writing practices are clarified through the use of numerous examples.

The basic components of a doctoral thesis are outlined and described, as are the elements of complete and accurate scholarly references, and detailed descriptions of writing practices are clarified through the use of numerous examples. PhD Success provides guidance for students familiar with English and the procedures of English universities, but it also acknowledges that many theses in the English language are now written by candidates whose first language is not English, so it carefully explains the scholarly styles, conventions and standards expected of a successful doctoral thesis in the English language.

Individual chapters of this book address reflective and critical writing early in the thesis process; working successfully with thesis supervisors and benefiting from commentary and criticism; drafting and revising effective thesis chapters and developing an academic or scientific argument; writing and formatting a thesis in clear and correct scholarly English; citing, quoting and documenting sources thoroughly and accurately; and preparing for and excelling in thesis meetings and examinations. 

Completing a doctoral thesis successfully requires long and penetrating thought, intellectual rigour and creativity, original research and sound methods (whether established or innovative), precision in recording detail and a wide-ranging thoroughness, as much perseverance and mental toughness as insight and brilliance, and, no matter how many helpful writing guides are consulted, a great deal of hard work over a significant period of time. Writing a thesis can be an enjoyable as well as a challenging experience, however, and even if it is not always so, the personal and professional rewards of achieving such an enormous goal are considerable, as all doctoral candidates no doubt realise, and will last a great deal longer than any problems that may be encountered during the process.

What Is a Noun? | Definition, Types & Examples

A noun is a word that represents a person, thing, concept, or place. Most sentences contain at least one noun or pronoun . For example, the sentences below contain anywhere from one to three nouns.

June is my favourite month .

Nouns are one of the main types of words in English, along with other parts of speech such as verbs. They are often, but not always, preceded by an article (‘the’, ‘a’, or ‘an’) or other determiner.

Other types of nouns

Frequently asked questions about nouns.

A complete sentence usually consists of at least a subject and a verb . The subject describes some person or thing, and the verb describes an action carried out by the subject.

In most cases, the subject is a noun or a pronoun. So the most basic role for a noun is to act as the subject for a verb that follows it.

David went out.

Nouns and pronouns can also play the role of object in a sentence. An object usually comes after the verb and represents something or someone that is affected by the action described. Objects can be direct or indirect:

• The direct object is someone or something that is directly acted upon by the verb.
• The indirect object is someone or something that receives the direct object.

Please give Jeremy some bread .

Noun phrases

When analysing sentence structure, it’s common to refer to noun phrases . A noun phrase is a noun or pronoun in combination with all the words that belong with it in the sentence, such as any articles, adjectives, or other determiners that modify the noun.

A noun phrase can consist of the noun or pronoun alone or of a much longer series of words (always including at least one noun or pronoun).

Pronouns are a much smaller set of words (such as ‘I’, ‘she’, and ‘they’) that are used in a similar way to nouns. They are primarily used to stand in for a noun that has already been mentioned or to refer to yourself and other people.

Like nouns, pronouns can function as the head of a noun phrase and as the subject or object of a verb. You can have a complete sentence consisting of just a pronoun and a verb (e.g., ‘He walks.’), just as you could with a noun (‘Jack walks.’).

Unlike nouns, some pronouns (mainly the personal pronouns ) change their forms depending on the grammatical context they’re used in. For example, the first-person pronoun is ‘I’ when it’s used as a subject and ‘me’ when it’s used as an object, whereas a noun like ‘dog’ would look the same in both cases.

That is beside the point.

An important distinction is made between two types of nouns, common nouns and proper nouns.

• Common nouns are more general. A common noun refers to a class of person, place, thing, or concept, but not to someone or something specific.
• Proper nouns are the names of specific people, places, things, or concepts. They are always capitalised to distinguish them from common nouns.

Another important distinction is between countable and uncountable nouns :

• Countable nouns (also called count nouns ) refer to things that can be counted. They can be preceded by an indefinite article or a number, and they can be pluralised. Most nouns are countable (e.g., ‘fact(s)’).
• Uncountable nouns (also called noncount nouns or mass nouns ) refer to things that can’t be counted. They should never be preceded by an indefinite article or a number, and they cannot be pluralised (e.g., ‘information’).

A common mistake in English is treating uncountable nouns as if they were countable by pluralising them or using an indefinite article. The solution to these problems is usually to rephrase using a related term or phrase that is countable.

• My previous two researches indicated that …
• My previous two studies indicated that …
• It’s important to account for bias in a research .
• It’s important to account for bias in research.
• It’s important to account for bias in a research project.

A distinction is often made between concrete nouns and abstract nouns.

• Concrete nouns refer to physical objects, places, or individuals: things or people that can be observed with the senses, such as ‘apple’, ‘hill’, ‘zebra’, and ‘Dorothy’.
• Abstract nouns refer to concepts, ideas, feelings, and processes that can’t be physically located, such as ‘grammar’, ‘justice’, ‘sadness’, and ‘relaxation’.

There’s no grammatical difference between concrete and abstract nouns – it’s just a distinction that’s made to point out the different kinds of things nouns can refer to.

A collective noun is a word used to refer to a group of people or things, such as ‘team’, ‘band’, or ‘herd’. A collective noun can also be a proper noun – for example, the name of a specific company or band.

A collective noun may appear to be singular (e.g., ‘team’) or plural (e.g., ‘The Beatles’) in form, and there’s some disagreement about whether they should be treated as singular or plural grammatically. The following applies for US vs. UK English .

• In US English , it’s standard to treat collective nouns as singular, regardless of whether they look plural or not.
• In UK English , the same words may be treated as plural or singular depending on the context – for example, treated as plural when you’re emphasising the individual members of the group, singular when you’re emphasising the overall collective.

A gaggle of geese is the most threatening thing you’re likely to encounter at the park.

There are many nouns in English (more than any other part of speech), and accordingly many ways of forming nouns and using them. Some other important types of nouns are:

• Possessive nouns
• Attributive nouns
• Appositive nouns
• Generic nouns

A possessive noun is a noun that’s followed by an apostrophe (’) and the letter ‘s’ to indicate possession (e.g., ‘my father’s house’).

To indicate possession with a plural noun that ends in ‘s’, you just add the apostrophe after the ‘s’, and don’t add an extra ‘s’ (e.g., ‘my parents’ house’).

A gerund is a noun that is identical to the present participle (the ‘-ing’ form) of a verb. These are typically nouns that describe the same activity as the verb they were formed from, such as ‘driving’, formed from the present participle of ‘drive’.

Attributive nouns are nouns that are used like adjectives, to modify another noun. For example, ‘company’ is an attributive noun in the phrase ‘company policy’.

Even though attributive nouns work similarly to adjectives, they’re still classed as nouns. This is because they don’t fulfill all the requirements of adjectives. For example, they have to appear before the noun – it wouldn’t make sense to say ‘a policy that is company’.

An appositive noun (or appositive noun phrase) is a noun that comes after another noun to provide additional information about it.

If the appositive provides essential information (i.e., it wouldn’t be clear who or what you are referring to without it), it’s written without any extra punctuation. If it provides extra information that is not essential, it’s surrounded by commas .

A generic noun is a noun that is used to refer to a whole class of things (or people, places, etc.). They can be plural or singular, and they may appear with a definite article, an indefinite article, or no article.

The same noun may be used generically in some contexts and not others. For example, it would be equally possible to use the nouns in the sentences below in a non-generic way (e.g., ‘the people I know best are my brothers’; ‘my father operated a printing press’).

A noun is a word that represents a person, thing, concept, or place (e.g., ‘John’, ‘house’, ‘affinity’, ‘river’). Most sentences contain at least one noun or pronoun .

Nouns are often, but not always, preceded by an article (‘the’, ‘a’, or ‘an’) and/or another determiner such as an adjective.

There are many ways to categorize nouns into various types, and the same noun can fall into multiple categories or even change types depending on context.

Some of the main types of nouns are:

• Common nouns and proper nouns
• Countable and uncountable nouns
• Concrete and abstract nouns

Pronouns are words like ‘I’, ‘she’, and ‘they’ that are used in a similar way to nouns . They stand in for a noun that has already been mentioned or refer to yourself and other people.

Pronouns can function just like nouns as the head of a noun phrase and as the subject or object of a verb. However, pronouns change their forms (e.g., from ‘I’ to ‘me’) depending on the grammatical context they’re used in, whereas nouns usually don’t.
