Master Thesis or Master’s Thesis – Which Is Correct?

When an individual pursues a degree, they frequently have to produce a thesis, as part of the requirements to graduate. What is the correct form to talk about it? Should we say “Master Thesis” or “Master’s Thesis”?

We want to know the correct form and appropriate way to use it.

“Master’s Thesis”, with an apostrophe, is the correct and acceptable form because the idea behind this phrase is “the thesis of a master”. The meaning of the expression “Master’s Thesis” requires the appropriate use of the possessive form to complement it. Consequently, “Master Thesis” is incorrect and should be avoided.

master thesis or master's thesis

Take a look at the examples below:

  • Matthew has an unpublished master thesis. (incorrect)
  • Matthew has an unpublished master’s thesis.
  • Christina’s goal is to finish her master thesis by the end of the year. (incorrect)
  • Christina’s goal is to finish her master’s thesis by the end of the year.

“Master Thesis” without the possessive form is incorrect and should never be used. For the proper meaning to be conveyed, it must be clear that the thesis belongs to a master. Consequently, the possessive form must be adequately present in the phrase.

“Master’s Thesis” is the complete, correct form we should use, in any circumstance, to talk about the thesis a graduate must prepare to meet the requirements to graduate.

Master Thesis

“Master Thesis” is a common incorrect form for the phrase “Master’s Thesis”. It’s a misspelling that lacks the apostrophe – which would be what indicates to whom the thesis belongs. It’s simply incorrect and incomplete, and should always be avoided.

Take a look at the examples below, that show “Master Thesis” being used incorrectly, followed by a corrected version of the same sentence:

  • Have you completed your master thesis? (incorrect)
  • Have you completed your master’s thesis?
  • The master thesis turned out to be more difficult than I thought. (incorrect)
  • The master’s thesis turned out to be more difficult than I thought.
  • John feels like his master thesis is missing something. (incorrect)
  • John feels like his master’s thesis is missing something.

“Master Thesis” is an incomplete form. It’s not an awful grammatical mistake, but it makes an immense difference in how a message sent by an expression is perceived.

“Master Thesis” is meant to indicate who’s the master of the thesis, and without the appropriate possessive form, it’s not possible to be accomplished. You should always avoid using “Master Thesis”.

Master’s Thesis

“Master’s Thesis”, with the apostrophe, is the correct form for this phrase. Because it contains the appropriate possessive form, it makes it clear to whom the thesis belongs. It’s complete and acceptable. You should always use this form to talk about any “Master’s Thesis”, in any scenario.

  • What’s your master’s thesis on?
  • The master’s thesis Howard defended was incredible.
  • How long should a master’s thesis be?
  • Claire’s master’s thesis was clear and concise.
  • What are the guidelines for writing a master’s thesis?
  • I need to choose what my master’s thesis will be about.

Masters Thesis

“Masters Thesis”, with an “s” after “Master” is just another incorrect form for the phrase “Master’s Thesis”. By adding the “s” without an apostrophe, this expression fails to indicate to whom the thesis belongs. It’s incorrect and should always be avoided.

Let’s go over some examples that show “Masters Thesis” being used incorrectly, followed by a corrected version of the same sentence:

  • Jonathan’s masters thesis was messy. (incorrect)
  • Jonathan’s master’s thesis was messy.
  • Carolina’s masters thesis was perfect. (incorrect)
  • Carolinas master’s thesis was perfect.
  •  I asked the professor to review my masters thesis. (incorrect)
  •  I asked the professor to review my master’s thesis.

“Masters Thesis”, just like “Master Thesis”, is incomplete. The lack of an apostrophe between “r” and “s” makes this phrase lose its purpose, which is to convey to who the thesis belongs. You should always avoid it.

Which Is Used the Most?

Which one of those forms is used more often, “Master Thesis”, “Masters Thesis”, or “Master’s thesis”? Take a look at the graph from Google Ngram Viewer below.

master thesis or master's thesis or masters thesis

The correct form “Master’s Thesis”, with the appropriate possessive form, is the prevalent phrase, which people use more frequently.

The two incorrect phrases, which are “Master Thesis” and “Masters Thesis” are used much less and seem to be fighting for the lowest position on the graph. As you can see, they are very close together and have already swapped places at the bottom of the graph.

Always avoid using “Master Thesis” and “Masters Thesis”, because they are incorrect, unacceptable forms.

Final Thoughts

“Master’s Thesis” is an expression that means “the thesis of a master”. Because of the strong sense of belonging it presents, it’s important to use it with the correct possessive form, including an apostrophe. “Master’s Thesis” is the correct form. “Master Thesis” is incorrect and should always be avoided.

Thesis is an irregular plural noun that does not end in the typical -s / -es that regular plural noun forms take.

Whats the Plural of Thesis: Understanding Singular and Plural Forms

  • 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.

What’s the Plural of Thesis?

The proper plural of thesis is “theses.” This transformation is part of a broader pattern in the English language where certain nouns change their ending to reflect a plural state.

Below, a comparison is made to illustrate the standard singular to plural transformation for nouns ending in -is:

Key Points about the pluralization of “thesis”:

  • The plural follows a specific rule of changing the ‘-is’ ending to ‘-es’.

Usage in Academia:

It denotes a statement that a writer intends to support and prove. In academic circles, thesis often refers to a document that presents the author’s research and findings and is submitted in support of candidature for a degree or professional qualification.

Etymological Background

The journey of the word from its Greek roots to the modern English language reflects the changing dynamics of educational and scholarly practices over the centuries.

As a carryover from Greek to Latin, the word made its way into English, maintaining its original Greek plural form:

Usage in Academia

In academia, the word has been used since the late Middle Ages to denote a scholarly work written by students aiming to obtain a university degree. Over time, the use of thesis expanded from merely referring to a proposition to a lengthy document providing evidence of comprehensive research.

Historical Evolution:

  • Middle Ages : Referred to propositions for a degree.
  • Renaissance : Emphasized individual research.
  • Modern Usage : Extensive research documents for higher education degrees.

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.

Master Thesis or Master’s Thesis?

plural of master's thesis

The correct term to refer to a thesis produced for a master’s degree is master’s thesis . E.g., “His master’s thesis focused on mosquito biting patterns.” The term master thesis is less common, and some regard it as incorrect. However, you can also interpret it as the primary thesis .

The correct grammatical version is master’s thesis . Furthermore, this version is far more common than the version without an apostrophe.

  • I wrote a master’s thesis in less than a month

You need the apostrophe to show that the thesis belongs to the master in the same way you need the apostrophe to say that the student belongs to the master’s program when you write:

  • Master’s student

Furthermore, you will see people using the term master thesis , which is incorrect if you want to say the thesis belongs to the student.

However, the problem with the term master thesis is that it can be grammatically correct , but only if you interpret the word master as an adjective describing the thesis .

Therefore, instead of being a thesis belonging to the master’s program , it becomes the master , as in main, primary, or principal.

  • He wrote a master thesis on the social impacts of inflation.

Now you have learned the basics regarding the correct version of master’s thesis . Keep reading the rest of the page to learn more about how you can avoid making mistakes with master’s thesis and master thesis .

Master’s Thesis

The term master’s thesis is the correct version to state the thesis belongs to the master’s student.

To indicate possession of the thesis by the student, you need to include an apostrophe to create a singular possessive.

Take a look at these examples to see how to correctly use master’s thesis :

  • Her master’s thesis helped her secure a job with the government.
  • His master’s thesis focused on the impacts of climate change in coastal regions.
  • She received high praise from her professors for the originality of her master’s thesis .
  • The research he conducted for his master’s thesis was later published in a renowned scientific journal.
  • After months of hard work, she finally submitted her master’s thesis to the university’s review committee.

Furthermore, you do not need to use a capital letter for master’s or thesis .

Master Thesis

The term master thesis is a little tricky because it can be correct and incorrect.

Firstly, to indicate that the thesis belongs to the master’s student , which is a noun, using master thesis is grammatically incorrect. You need to use the apostrophe in the sentence to indicate ownership.

However, although this is the case, some people still use the version without an apostrophe for the same purpose.

  • Incorrect: She is presenting her master thesis this afternoon.
  • Correct: She is presenting her master’s thesis this afternoon.

Secondly, if you interpret the word master as an adjective, then you could, in theory, say:

  • She just finished writing a master thesis on pollution.

In the example above, you can interpret the word master as a synonym for primary.

Finally, if you write the full name of a degree program , you need to use Master with no apostrophe and a capital letter.

  • He wrote a Master of Science thesis on bacterial infections.

You will see in the above example that Master has a capital letter and thesis does not. This is because we are referring to the master’s program in full, but we refer to the thesis in a general sense.

However, in some cases, such as on the front cover, you also need to capitalize thesis .

  • The front cover of my thesis says Master of Arts Thesis in big, bold letters.

Masters Thesis

The term masters thesis is incorrect because it is missing the apostrophe that shows that the thesis belongs to the master’s student.

  • Incorrect: The masters thesis was written extremely badly.
  • Correct: The master’s thesis was written extremely badly.

Without the “s” at the end of master , there are some circumstances in which it can be correct without an apostrophe. However, with the “s” included, it is wrong to omit the apostrophe.

Masters’ Thesis

The term masters’ thesis is wrong because the thesis belongs to either a master’s student or a master’s degree. Therefore, using the plural possessive form rather than the singular possessive is incorrect.

  • Incorrect: Her masters’ thesis was the best I have ever read.
  • Correct: Her master’s thesis was the best I have ever read.

In addition, if you want to mention multiple theses , you should use the plural form of thesis:

  • I have to grade four master’s theses this weekend.
  • The university library has copies of all the master’s theses from the past decade.
  • Among the master’s theses I’ve read, hers had the most compelling arguments.
  • The department will showcase excerpts from this year’s top master’s theses during the annual seminar.

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.

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:

Nouns that End in Us

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

Nouns that End in Is

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

Nouns that End in On

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

Plurals That Are the Same as Singulars

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

Words That Look Like Plural Nouns but Are Singular Nouns

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

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:

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.
