plural of thesis dictionary

Plural Nouns

In general, a noun is a person, place, or thing. A proper noun is a specialized name for a specific person, place, or thing. Proper nouns are always capitalized (e.g., “Crayola”). Nouns can be singular (i.e., only one) or plural (i.e., more than one).

To make a noun plural, add “s” (e.g., “dogs” is the plural form of “dog”), “es” (e.g., “boxes” is the plural form of “box”; add “es” to most nouns that end in “ch,” “s,” “sh,” “x,” and “z” to make them plural), and sometimes “ies” (e.g., “babies” is the plural form of “baby”; see the Notes section for exceptions to this grammar guideline ) to the end of the noun.

Irregular plural nouns , which include terms like “women,” “men,” “children,” “alumni,” “feet,” “mice,” “data,” and so forth, usually are not made plural by adding “s,” “es,” or “ies” to their endings. However, some irregular plural nouns have the same endings as regular plural nouns, such as “leaves,” “knives,” “analyses,” and “theses.”

Plural nouns are covered in the seventh edition APA Style manuals in the Publication Manual Sections 4.18 and 6.11 and the Concise Guide Sections 2.18 and 5.1

Plural surnames

Usually, a surname is made plural by adding an “s” to the end of it (e.g., “Ayubis” is the plural form of the surname “Ayubi”), but there are exceptions. Add “es” to most surnames that end in “ch,” “s,” “sh,” “x,” and “z” to make them plural: for example, “Burch” becomes “Burches,” “Jones” becomes “Joneses,” “Nash” becomes “Nashes,” “Knox” becomes “Knoxes,” and “Hernández” becomes “Hernándezes.”  

However, if the “ch” at the end of a surname is pronounced with a hard “k,” like “Bach,” add “s” to the end of the surname to make it plural: “Bachs” (the same is true for common nouns ending in a hard “ch”: “stomachs”). Likewise, if the “x” at the end of a surname is silent, like “Rioux,” make the surname plural by adding an “s” to the end of the name: “Riouxs.”

Plural versus possessive

Although there are many unique ways to form plural nouns, please note that placing an apostrophe “s” or just an apostrophe after an “s” at the end of a noun is not one of them. “Tuesday’s” and “cat’s” are never the plurals of “Tuesday” and “cat”; the plurals are “Tuesdays” and “cats.” In general, an apostrophe “s” is used to form the possessive case of a noun .

Some nouns are spelled the same way in their singular form as they are in their plural form (e.g., “fish,” “moose,” “sheep”). Other nouns do not have a singular form and are always spelled in the plural form (e.g., “clothes,” “eyeglasses,” “scissors”). Conversely, some nouns do not have a plural form (e.g., “homework,” “milk,” “advice”).

Also, to make an abbreviation plural, add an “s” to the end of the abbreviation. For example, “HCP” is the abbreviation of “health care provider” and “HCPs” is its plural form.

The spelling guidelines on this page serve as general pluralization recommendations and are not comprehensive. They are not specific to APA Style and can be found in many dictionaries and other style guides. The APA Style Experts frequently consult the Merriam-Webster.com Dictionary for their spelling guidance .

Some common examples of nouns in their singular and plural forms are presented next.

a “Attornies” is not the plural form of “attorney” because the letter that precedes the “y” is a vowel (i.e., an “e”) and not a consonant . In general, do not change nouns that end in “y” to “ies” to make them plural if the letter that precedes the “y” is a vowel; add an “s” to the end of the noun to make it plural.

b “Families” ends in “ies” because the letter that precedes the “y” in “family” is a consonant (i.e., an “l”). However, there are exceptions to this guidance. For example, “moneys” and “monies” are acceptable plural forms of “money.” When a term has more than one plural form, use your best judgment to determine which spelling is more appropriate to use in your work.

c The term “persons” is sometimes used in research settings to refer to groups of a specific number and in a legal context such as “missing persons” or “persons of interest.” Nevertheless, “people” is the preferred plural form of “person.”

d “Peoples” may be used to describe specific ethnic communities such as “Indigenous Peoples” or “First Peoples.”

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.

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.

The collection of theses are ready for publication.

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.

Origin of the word “thesis”

Thesis / theses are of Greek origin.

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.

Table of Contents

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’.
• This pattern is consistent with other Greek-derived words.
• The pronunciation changes with the plural form, ending in “-eez.”

To clarify usage, consider these examples:

• Singular: The student’s thesis was commended for its clarity.
• Plural: The professor read all the submitted theses before the conference.

Singular Form of Thesis

The singular form of ‘thesis’ is of notable interest due to its origins and distinct pluralization.

Origination and Definition:

• Etymology : Derived from the ancient Greek word τίθημι (tithēmi), which means “to put” or “to place.”
• Meaning : It is a statement or theory put forward to be maintained or proved.

Usage in Academia:

• A significant piece of writing prepared by a student to obtain a university degree or diploma.
• Often involves original research and substantiates a particular view or argument.

Table 2: Contextual Examples

Definition of Thesis

A thesis is a substantial piece of scholarly writing that is typically required to obtain a master’s or doctoral degree. It represents the author’s research and findings in their chosen field of study. A thesis serves as evidence that the student has acquired the knowledge necessary to be considered a scholar in the field. Here, two key aspects of a thesis will be described through tables:

Purpose and Composition of a Thesis:

Characteristics of a Thesis:

• Focused : It should have a clear, concise premise or central argument.
• Researched : Employs rigorous methodologies to gather and analyze data.
• Structured : Contains defined sections that present information logically.
• Cited : Includes proper citations of sources that support or contrast the thesis.
• Reviewed : Undergoes scrutiny by academic peers or supervisors.

Common Irregular Plurals:

Origin of the Word Thesis

The term thesis originates from the ancient Greek word θέσις (thésis), which means “a proposition” . Historically, this term has played a crucial role in both rhetorical and academic contexts. 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

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

Areas of Impact:

• Academic Research : Reflects comprehensive study in a field.
