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.

Plural of Thesis: A Quick Guide for English Learners

By: Author ESLBUZZ

Posted on Last updated: October 11, 2023

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.

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.

Saints on the border: plural marriage, power, and the remaking of the Latter-Day Saints on the U.S.-Mexico border, 1885-1925

This dissertation examines how Latter-day Saints reconciled themselves to the Church of Jesus Christ of Latter-day Saints’s renunciation of plural marriage during the post-Manifesto period. For much of the twentieth century, the prevailing consensus among scholars of Mormonism was that after a protracted legal struggle over plural marriage–culminating in the federal antipolygamy campaigns of the 1880s–the Church unequivocally renounced plural marriage with the Woodruff Manifesto of 1890. While a growing number of scholars have begun to examine post-Manifesto plural marriage in the United States, 1890 remains a widely accepted marker that signaled the end to the Church’s official participation in plural marriage and marks the beginning of Latter-day Saints’ largely successful assimilation into the American body politic, a process that was concretized with Utah statehood in 1896. This dissertation fundamentally disrupts that narrative. It argues that the battle over plural marriage extended beyond the nation’s borders and persisted well into the 20th century. During the height of the U.S. antipolygamy raids, the Church sought out land south of the U.S.-Mexico border as a refuge for polygamous families fleeing criminal prosecution. After the Woodruff Manifesto, nine Mormon “colonies” in Sonora and Chihuahua operated as a liminal space where Latter-day Saints ensured plural marriage’s survival beyond the punitive reach of the U.S. government. Between 1890 and 1904, those settlements became the nucleus of a transnational network wherein church leaders in Salt Lake City continued to sanction and perform polygamous unions for their brethren in Mexico, thereby observing the word--if not the spirit--of the Woodruff Manifesto. That network relied upon covert methods wherein Latter-day Saints could enter into polygamous unions without attracting the scrutiny of non-Mormons to church leaders or themselves. When the 1904-1907 U.S. Senate hearings over the seating of the Mormon Senator-elect Reed Smoot renewed the nation’s interest in the intimate lives of Latter-day Saints, uncovered cases of post-Manifesto plural marriages performed in Mexico gave material credence to ongoing rumors that the Church had violated the Woodruff Manifesto and flouted mainstream American sexual mores. In the wake of the political fallout from the hearings, the Church issued a final renunciation of plural marriage with a “Second” Manifesto in 1904 that renounced plural marriage within and beyond U.S. borders. However, church leaders found that a growing number of Mexico colonists--who considered the practice the bedrock of their community and the singular assurance of their spiritual exaltation--struggled to convert themselves to the Church’s new commitment to monogamy. To the consternation of Church leaders, some Mexico colonists rejected the 1904 declaration outright and claimed the marital authority once reserved for the highest-ranking Latter-day Saints for themselves. Over the next decade, the Mexico settlements became the arena for a fraught internal conflict over marital and spiritual authority. By the 1920s, excommunications and disciplinary proceedings within the Church’s ecclesiastical courts enabled the Church to regain control over marital practices but also produced lingering trauma for polygamous families forced to carve a new place for themselves within a modern and monogamous Church. By extending both the geographic scope and the periodization of Mormon plural marriage, this dissertation recovers transnational spaces as an important dimension of analysis for the polygamous Mormon experience. By reframing the decline of polygamy as an internal, inter-Mormon conflict, it makes a substantive contribution to historiography that underscores Latter-day Saints’ uneven and painful transition to monogamy.
