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.

Sharing is caring!

Do you know the plural of thesis? Understanding the correct plural of thesis is important not only for academic writing, but for general communication as well. Whether you’re discussing multiple research papers or simply trying to sound knowledgeable in a conversation, using the correct plural form can help you make a good impression and avoid any confusion or misunderstandings.

Plural of Thesis

Plural of Thesis: A Quick Guide for English Learners

Definition and Plural of Thesis

When writing a research paper or dissertation, the central argument or main point is known as a thesis. A thesis is a statement or proposition that is put forward as a premise to be maintained or proved. It is a crucial element of academic writing and is often required for a degree or certification.

The plural of thesis is “theses.” In English, most nouns form the plural by adding an “s” at the end. However, “thesis” is one of the few exceptions to this rule. The word “thesis” has a Greek root, and “theses” is how it is pluralized in that original language.

Singular Plural
Thesis Theses

It is important to note that “theses” is the only way to make the noun “thesis” plural. There is no alternative form of the plural for this word.

In academic writing, the plural form “theses” is commonly used when referring to multiple research papers or dissertations. For example, “I have read several theses on this topic, and they all have different viewpoints.”

When to Use Thesis and Its Plural Form

When writing academic papers or conducting research, it is important to understand when to use the word “thesis” and its plural form, “theses.” Here are some guidelines to help you use these words correctly:

  • Use “thesis” when referring to a single research paper or dissertation that presents a specific argument or viewpoint.
  • Use “theses” when referring to multiple research papers or dissertations.
  • Remember that “thesis” is a singular noun and “theses” is its plural form.
  • Be aware that “thesis” has a Greek root and follows the same pluralization rule as other Greek words ending in “-is,” such as “crisis” and “analysis.” They become “crises” and “analyses,” respectively.
  • Keep in mind that “thesis” can also refer to a statement or proposition that is put forward for consideration or discussion. In this case, the plural form would be “theses.”
  • When citing multiple theses in a paper, use “theses” to indicate the plurality. For example, “The theses presented in this paper all support the idea that…”

Examples of Thesis and Its Plural Form in Sentences

If you are wondering how to use the word “thesis” in a sentence, here are a few examples:

  • Your thesis statement should be clear and concise.
  • The professor asked us to submit our theses by the end of the semester.
  • The thesis of the article is that climate change is caused by human activity.
  • She spent months researching and writing her thesis on the history of feminism .
  • The committee was impressed by the depth and originality of his thesis.

As you can see, “thesis” is used to refer to a statement or argument put forth by a writer or speaker, as well as a research paper written by a student to earn a degree.

Now, let’s take a look at the plural form of “thesis.” According to Grammar Monster, the only correct way to form the plural of “thesis” is “theses.” Here are some examples of how to use “theses” in a sentence:

  • The library has a collection of theses written by graduate students.
  • The professor asked us to read several theses on the topic before starting our own research.
  • The theses presented at the conference covered a wide range of topics.
  • The committee was impressed by the quality and originality of the theses submitted.

Plural Noun Rules for Regular Nouns

When forming the plural of regular nouns, there are some standard rules to follow. These rules apply to most English nouns, including “thesis.” Here are the basic guidelines:

  • For most singular nouns, simply add an “-s” to the end to form the plural. For example, “book” becomes “books,” “car” becomes “cars,” and “house” becomes “houses.”
  • If the singular noun ends in “-s,” “-x,” “-z,” “-ch,” or “-sh,” add “-es” to form the plural. For example, “bus” becomes “buses,” “box” becomes “boxes,” “buzz” becomes “buzzes,” “church” becomes “churches,” and “dish” becomes “dishes.”
  • If the singular noun ends in a consonant followed by “-y,” change the “-y” to “-ies” to form the plural. For example, “city” becomes “cities,” “baby” becomes “babies,” and “story” becomes “stories.”
  • If the singular noun ends in a vowel followed by “-y,” simply add an “-s” to form the plural. For example, “boy” becomes “boys,” “key” becomes “keys,” and “day” becomes “days.”

It’s important to note that there are some irregular nouns that don’t follow these rules. For example, “child” becomes “children,” “foot” becomes “feet,” and “tooth” becomes “teeth.” However, “thesis” is a regular noun, so it follows the standard rules for forming the plural.

Plural Noun Rules for Irregular Nouns

When it comes to forming the plural of nouns in English, there are some general rules that apply to most words. However, there are also many irregular nouns that don’t follow these rules and have unique plural forms. In this section, we’ll go over some common irregular plural nouns and the rules for forming their plurals.

List of Common Irregular Plural Nouns

Here are some examples of irregular plural nouns that you may come across:

Singular Plural
Child Children
Foot Feet
Goose Geese
Man Men
Mouse Mice
Tooth Teeth
Woman Women

Nouns that End in Us

Nouns that end in “us” often have a plural form that ends in “i”. For example:

Singular Plural
Cactus Cacti
Focus Foci
Radius Radii

Nouns that End in Is

Nouns that end in “is” may have a plural form that ends in “es”. For example:

Singular Plural
Analysis Analyses
Basis Bases
Crisis Crises

Nouns that End in On

Nouns that end in “on” may have a plural form that ends in “a”. For example:

Singular Plural
Criterion Criteria
Phenomenon Phenomena
Vertex Vertices

Plurals That Are the Same as Singulars

Some nouns have the same form for both the singular and plural. For example:

Singular Plural
Deer Deer
Fish Fish
Sheep Sheep

Words That Look Like Plural Nouns but Are Singular Nouns

Some words may look like plural nouns but are actually singular nouns. For example:

Singular Plural
News
Mathematics
Physics

Collective Nouns and List

When it comes to forming the plural of nouns, collective nouns can be a bit tricky. A collective noun refers to a group of people or things as a single entity. For example, “team” is a collective noun because it refers to a group of individuals working together towards a common goal.

The challenge with collective nouns is deciding whether to treat them as singular or plural. In American English, collective nouns are usually treated as singular, while in British English, they can be treated as either singular or plural depending on the context.

Here are some examples of collective nouns and how they can be treated in different contexts:

Collective Noun Singular Example Plural Example
audience The audience is enjoying the show. The audience are clapping their hands.
family My family is going on vacation. My family are all different ages.
staff The staff is working hard. The staff are taking their lunch breaks.

As you can see, the choice of whether to use a singular or plural verb depends on whether you are referring to the group as a single entity or as individuals within the group.

When it comes to forming the plural of collective nouns, the same rules apply as for regular nouns. For example, the plural of “team” is “teams”, and the plural of “family” is “families”.

Plural Nouns vs. Possessive Nouns

When it comes to forming the plural of nouns, there are standard rules that apply to most words in the English language. However, there are some exceptions, such as the word “thesis.” The plural of “thesis” is “theses,” and this is the only correct way to form the plural of this word.

On the other hand, when it comes to forming possessive nouns, there are a few rules to keep in mind. Here are some key points to remember:

  • For singular nouns, add an apostrophe and an “s” to show possession. For example, “the thesis’s conclusion” means the conclusion belonging to the thesis.
  • For plural nouns that end in “s,” add only an apostrophe to show possession. For example, “the theses’ conclusions” means the conclusions belonging to the theses.
  • For plural nouns that do not end in “s,” add an apostrophe and an “s” to show possession. For example, “women’s rights” means the rights belonging to women.

It’s important to note that possessive nouns should not be confused with plural nouns. While they may look similar, they serve different grammatical functions. Possessive nouns show ownership or possession, while plural nouns simply refer to more than one of something.

Common Mistakes with Plural Nouns

When it comes to forming the plural of nouns, there are some common mistakes that are made. Here are a few things to keep in mind when forming the plural of the word “thesis” and other nouns:

Adding an Apostrophe

One common mistake is adding an apostrophe to a noun to make it plural. For example, “the thesis’s” instead of “the theses.” This is incorrect and should be avoided.

Irregular Plurals

Some nouns have irregular plurals that do not follow the standard rules. For example, “child” becomes “children” and “goose” becomes “geese.” It is important to learn these irregular plurals to avoid mistakes.

Confusion over Plurals

Some nouns, like “thesis,” can cause confusion over their plural form. “Theses” is the only correct way to make “thesis” plural. Other words that end in “-is” may also have irregular plurals, such as “crisis” becoming “crises.”

Using Incorrect Count Nouns

It is important to use the correct count nouns when referring to multiple instances of something. For example, “studies” instead of “researches,” and “pieces of evidence” instead of “evidences.” Using the incorrect count noun can make your writing sound awkward or confusing.

Q. Greetings from New Zealand. May I please ask you what is the plural of “thesis” and whether this word is of Latin or Greek origin? Many thanks.

A. For this sort of thing, we at the University of Chicago Press must rely on the lexicographers. The plural, according to Merriam-Webster and others, is “theses.” As for origin, according to the Oxford English Dictionary, “thesis” was

[o]riginally and properly, according to ancient writers, [t]he setting down of the foot or lowering of the hand in beating time, and hence (as marked by this) the stress or ictus ; the stressed syllable of a foot in a verse; a stressed note in music.

Among the ancient writers offered as proof are the authors of Greek fragments studied by Rudolf Westphal in his Die Fragmente und die Lehrsätze der griechischen Rhythmiker from 1861. Later Latin writers inverted this meaning, but the one that has generally survived today is the setting down, not of the foot, but of a proposition. So Greek it is.

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 .

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

Thesis Meaning: Here’s What It Means and How To Use It

mm

Your writing, at its best

Understanding what a thesis is can help you improve your written and spoken communication.

thesis is the plural of

There are countless different contexts where this word is used, and knowing how to properly use it can help you communicate effectively in your field. If you want to be the most effective and successful communicator possible, feel free to read and learn about this essential word ! 

This is everything you need to know about what this word means, where it comes from in etymology, and how it is used.

What Is a Thesis? 

The definition of thesis (ˈθi sɪs, ˈθiːsɪs, the-sis, plural theses) in American English is the main idea presented in an essay. In other words, the central message of the piece. Behind every literary device and rhetorical strategy stands a thesis. Thesis statements don’t just appear at the beginning of your paper; they should be woven into every sentence you write. 

Your thesis statement will probably be one of two things: an assertion that something is true or an argument for why something should be done (or not done). 

What Is a Thesis Statement?

A Thesis statement is a sentence that contains the main idea of a written work.

All other sentences in a paper should explain, prove, or describe this main idea. Thesis statements are often used in reports to express a central message of an essay or article. Researchers commonly use them to propose a hypothesis and then test it with evidence from their study.

What Are Some Synonyms of Thesis?

If you look in a thesaurus for word lists of synonyms for the word thesis, you’ll likely find words including: 

  • Point of View
  • Proposition
  • Dissertation

What Is a Thesis in the Academic World? 

When it comes to the world of academics, the word thesis has another similar yet different meaning. 

A thesis is a long-form piece of writing, often a research paper, that is used as the final project of a university degree, like a master’s degree. 

What Is a Master’s Thesis?

A master’s thesis is a project that contains lots of original research and is used to cap off an academic degree. It is how a student takes an unproved statement and then proves it through extensive writing. 

When Would You Write a Thesis?

If you’re studying a language like Greek, Spanish, Arabic, or Late Latin, you’ll likely have to do an extensive study — and write a thesis — to prove your knowledge of the language. The main goal of a thesis is to establish the synthesis of knowledge that a student is capable of and ensure that they can operate well in the academic world. 

How Do You Start Writing a Thesis?

Before a student or researcher begins writing a paper, they must have a thesis statement. This thesis statement is one sentence that describes how you will support your argument and what evidence you will provide in your paper. In many cases, it is the last sentence of your introduction paragraph and appears again as the first sentence of the body paragraph:

A thesis statement usually evolves only after considerable reading, writing, and thinking has been done on your topic. Your thesis changes and develops as you write it, so by the time you arrive at the end, you will know what your paper is about and should be able to sum it up clearly in a sentence or two.

What Is the Etymology of the Word Thesis? 

The word thesis comes from the Greek word θέσις (thésis), which means “placement” or “setting.” The term was first used in English in 1632 by William Lilly. As time has progressed, the word has entered into many different languages, including Latin tithenai , French, and Middle English. 

Throughout its different stages of development, the word has remained relatively the same. However, this word’s collocations and more specific meanings have gradually changed over the years. 

Luckily, as long as you’re only sticking to English, thesis is a word with meanings that are relatively consistent and easy to understand! 

What Are Some Example Sentences Using the Word Thesis?

One of the best ways to learn how to use a word is by seeing it in use in the context of actual-world sentences and conversations. 

Here are some excellent examples of thesis being used in everyday sentences, so you can start using the word for yourself! 

As he started his conversation, the lowering of his voice enticed everyone to listen intently to his thesis presentation.

The first research stage for her doctoral thesis meant studying the Hegelian people.

Mr. Tese’s master’s thesis primarily focused on a tiny part of a metrical foot in poetry, which was reasonably interesting for many poets.

My entire paper’s central thesis was based on how the downbeat is not the most crucial part of music — the backbeat is.

My professor keeps telling me that the thesis statement is, by far, the most critical part of any essay, and I’m starting to believe her.

It took nearly six months to write the first draft of my thesis, which was really exhausting.
