Etymology [ edit ].

From Late Middle English thesis ( “ lowering of the voice ” ) [1] and also borrowed directly from its etymon Latin thesis ( “ proposition, thesis; lowering of the voice ” ) , from Ancient Greek θέσῐς ( thésis , “ arrangement, placement, setting; conclusion, position, thesis; lowering of the voice ” ) , from τῐ́θημῐ ( títhēmi , “ to place, put, set; to put down in writing; to consider as, regard ” ) [2] [3] (ultimately from Proto-Indo-European *dʰeh₁- ( “ to do; to place, put ” ) ) + -σῐς ( -sis , suffix forming abstract nouns or nouns of action, process, or result ) . The English word is a doublet of deed .

Sense 1.1 (“proposition or statement supported by arguments”) is adopted from antithesis . [2] Sense 1.4 (“initial stage of reasoning”) was first used by the German philosopher Johann Gottlieb Fichte (1762–1814), and later applied to the dialectical method of his countryman, the philosopher Georg Wilhelm Friedrich Hegel (1770–1831).

The plural form theses is borrowed from Latin thesēs , from Ancient Greek θέσεις ( théseis ) .

What’s the Plural of Thesis? (Thesises? Theses?)

• November 13, 2022

What’s the plural of “thesis”?

Thesis , (and its plural theses ) is an example of one of the many common English words that has roots elsewhere. In this case, thesis is a word that has roots all the way back to Ancient Greek. Like other similarly structured words: diagnosis , synthesis , analysis , oasis , crisis , nemesis and the like, thesis is by no means the only frequently used Greek word that’s made it to Modern English.

What’s the singular of thesis?

Thesis is a singular noun and refers to one thing (or one thesis ).

What’s a thesis?

Merriam-Webster defines the noun thesis (plural theses ) as follows, “a dissertation embodying results of original research and especially substantiating a specific view especially : one written by a candidate for an academic degree.”

Nouns that end in -sis/ses

Thesis is an irregular plural noun that does not end in the typical -s / -es that regular plural noun forms take. This is so despite that theses plural does in fact end in the conventional -s/-es suffix. Why is it still considered irregular; then, given that it follows the regular plural form? Notice the following regular plural noun forms:

Thesis / theses operates differently. With these Greek words, the -ses does not simply  add onto the end of the singular form of the noun; instead, -ses replaces the singular noun’s suffixes, and effectively changes the entire spelling of the word (and arguably the word itself.)

Examples of “thesis” (singular) in sentences

His master thesis was on modal neural networks.

She wrote her thesis on Renaissance Nativity scenes.

We disagreed with the basic thesis of the report.

I’ve made a first draft of my thesis .

The student’s experiments helped her formulate a thesis to share with her professor and classmates.

Examples of “theses” (plural) in sentences

It must not be assumed that Luther’s ninety-five theses produced any considerable direct results.

Twenty years after Savonarola’s death Martin Luther made public his theses against indulgences.

Theses are generally examined by two or more specialists.

Theses is the plural form of the singular noun thesis.

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.

Have you ever met them before?

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.

• The plural of “thesis” adheres to the Greek-rooted pattern, changing the singular -is to a plural -es.
• Accurate use of “thesis” and “theses” reflects scholarly precision in both written and oral communication.
• Awareness of correct pluralization extends to other similar nouns ending in -sis, emphasizing the importance of understanding language origins.

It is crucial to use the word correctly in both singular and plural contexts to maintain the integrity of written and spoken communication. In the realm of academics, precision in language reflects the rigor of one’s research and argumentation. As such, understanding the transformation from “thesis” to its plural counterpart is more than a trivial detail; it reflects a deeper appreciation for the structure and history of the English language.

Did You Know?

English borrowed aegis from Latin, but the word ultimately comes from the Greek noun aigís , meaning “goatskin.” In ancient Greek mythology, an aegis was something that offered physical protection. It has been depicted in various ways, including as a magical protective cloak made from the skin of the goat that suckled Zeus as an infant, and as a shield fashioned by Hephaestus that bore the severed head of the Gorgon Medusa . The word first entered English in the 15th century as a noun referring to the shield or breastplate associated with Zeus or Athena. It later took on a more general sense of “protection” and, by the late-19th century, it had acquired the extended senses of “ auspices ” and “sponsorship.”

Letter: I take issue with the word 'creative' being used as a noun

• Apr 12, 2024
• 1 min to read

To the editor: Regarding Mitchell Chapman’s April 8 commentary " Why AI ‘art’ irks me ," I am in complete agreement with every point he makes.

My issue is with his use of the word “creative” as a noun. Mr. Chapman is far from alone in his use of the term. I’m always happy to hear it employed as an adjective — for instance, when someone gives my 4-year old daughter a compliment about her latest painting (“That’s so creative!”) or uses it in its more strictly utilitarian use (“the creative community”).

But I really dislike reading or hearing it used as a noun intended to classify people like me and the majority of my friends. It has a very strange ring to it, as if we were a recently discovered species. My oldest friend is a poet, also from the Berkshires. Many other friends are filmmakers, musicians, composers and so on. As a general term, “artists” is just fine. If someone is looking for something less lofty, then “members of the creative community” sounds about right.

I myself have zero patience with language policing. In this case, I feel that the word takes what we do and depersonalizes it, which is precisely the opposite of Mr. Chapman’s intentions in his fine commentary.

Kent Jones, Brooklyn, N.Y.
