The Difference Between Hypothesis and Theory

A hypothesis is an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true.

In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review. You ask a question, read up on what has been studied before, and then form a hypothesis.

A hypothesis is usually tentative; it's an assumption or suggestion made strictly for the objective of being tested.

A theory , in contrast, is a principle that has been formed as an attempt to explain things that have already been substantiated by data. It is used in the names of a number of principles accepted in the scientific community, such as the Big Bang Theory . Because of the rigors of experimentation and control, it is understood to be more likely to be true than a hypothesis is.

In non-scientific use, however, hypothesis and theory are often used interchangeably to mean simply an idea, speculation, or hunch, with theory being the more common choice.

Since this casual use does away with the distinctions upheld by the scientific community, hypothesis and theory are prone to being wrongly interpreted even when they are encountered in scientific contexts—or at least, contexts that allude to scientific study without making the critical distinction that scientists employ when weighing hypotheses and theories.

The most common occurrence is when theory is interpreted—and sometimes even gleefully seized upon—to mean something having less truth value than other scientific principles. (The word law applies to principles so firmly established that they are almost never questioned, such as the law of gravity.)

This mistake is one of projection: since we use theory in general to mean something lightly speculated, then it's implied that scientists must be talking about the same level of uncertainty when they use theory to refer to their well-tested and reasoned principles.

The distinction has come to the forefront particularly on occasions when the content of science curricula in schools has been challenged—notably, when a school board in Georgia put stickers on textbooks stating that evolution was "a theory, not a fact, regarding the origin of living things." As Kenneth R. Miller, a cell biologist at Brown University, has said , a theory "doesn’t mean a hunch or a guess. A theory is a system of explanations that ties together a whole bunch of facts. It not only explains those facts, but predicts what you ought to find from other observations and experiments.”

While theories are never completely infallible, they form the basis of scientific reasoning because, as Miller said "to the best of our ability, we’ve tested them, and they’ve held up."

• proposition
• supposition

hypothesis , theory , law mean a formula derived by inference from scientific data that explains a principle operating in nature.

hypothesis implies insufficient evidence to provide more than a tentative explanation.

theory implies a greater range of evidence and greater likelihood of truth.

law implies a statement of order and relation in nature that has been found to be invariable under the same conditions.

Plural of Hypothesis: Rules and Examples

By: Author ESLBUZZ

Posted on Last updated: November 13, 2023

Sharing is caring!

The plural of hypothesis is a topic of much debate among scientists and researchers. While some argue that “hypotheses” is the correct plural form, others insist that “hypothese” is the proper way to refer to multiple hypotheses. So, which one is correct? In this article, we will explore the history and etymology of the word “hypothesis” and examine the different arguments for each plural form. By the end of this article, you will have a better understanding of the plural of “hypothesis” and be equipped to use it accurately in your scientific writing.

Plural of Hypothesis

Definition and Plural of Hypothesis

If you are a scientist or a researcher, you are probably familiar with the term “hypothesis.” A hypothesis is an idea or explanation for something that is based on known facts but has not yet been proved. It is often used as a starting point for scientific research.

There are several key components of a hypothesis:

• Testability: A hypothesis must be testable through experimentation or observation. This means that it must be possible to collect data that can either support or refute the hypothesis.
• Falsifiability: A hypothesis must be falsifiable, meaning that it can be proven false if it is not supported by the data. This is important because it allows scientists to eliminate incorrect explanations and focus on more accurate ones.
• Specificity: A hypothesis must be specific in its predictions. It should clearly state what is being tested and what the expected outcome is.
• Relevance: A hypothesis must be relevant to the research question or problem being addressed. It should be based on existing knowledge and observations related to the phenomenon being studied.

The plural of “hypothesis” is “hypotheses.” Scientists base scientific hypotheses on previous observations that cannot be explained with the available scientific theories. Experimenters may test and reject several hypotheses before solving a problem. The noun “hypothesis” has a Greek root, which is the derivation of the plural “hypotheses.”

It is important to note that a hypothesis is not a proven fact. It is simply an idea that can be tested and either confirmed or rejected through experiments or further research. A hypothesis is often used to explain a phenomenon or to predict the outcome of an experiment.

In scientific research, hypotheses are crucial for advancing knowledge and understanding of the world around us. They help researchers to identify the gaps in current knowledge and to develop new theories and explanations. Hypotheses are also used to guide experiments and to determine the best methods for collecting and analyzing data.

When to Use Hypothesis and Plural of Hypothesis

When conducting scientific research, it is important to understand when to use the singular form “hypothesis” and when to use the plural form “hypotheses.” A hypothesis is a proposed explanation for a phenomenon that can be tested through experimentation or observation. Scientists use hypotheses to guide their research and to make predictions about the outcomes of experiments.

When discussing a single proposed explanation, you would use the singular form “hypothesis.” For example, “My hypothesis is that increased exposure to sunlight will lead to increased plant growth.”

On the other hand, when discussing multiple proposed explanations, you would use the plural form “hypotheses.” For example, “The researchers tested several hypotheses before arriving at a conclusion.”

It is important to note that the plural form “hypotheses” is not used to refer to multiple instances of the same hypothesis. In this case, you would still use the singular form “hypothesis.” For example, “The experiment was conducted multiple times to test the same hypothesis.”

Examples of Hypothesis and Plural of Hypothesis in Sentences

When it comes to forming the plural of hypothesis, it’s important to remember that “hypotheses” is the only way to make the noun “hypothesis” plural. Here are a few examples of how to use “hypothesis” and “hypotheses” in sentences:

Using “hypothesis”: 

• You have developed a hypothesis about the cause of the problem.
• My hypothesis is that the new treatment will improve patient outcomes.
• The scientist presented a compelling hypothesis about the origin of the universe.
• Before conducting any experiments, it’s important to develop a hypothesis to guide your research.

Using “hypotheses”: 

• The team’s hypotheses were all based on sound scientific principles, but only one was ultimately proven correct.
• The researchers had to revise their hypotheses several times as they collected more data.
• Without testing multiple hypotheses, it’s difficult to determine which one is the most accurate explanation for a given phenomenon.
• The team’s hypotheses were all based on different assumptions, which made it difficult to determine which one was correct.

As you can see, the plural form of “hypothesis” is used when referring to multiple hypotheses. It’s important to use the correct plural form to ensure clear communication.

In addition to using “hypotheses” as the plural form, it’s also important to use the correct verb agreement. For example:

Correct:  The hypotheses were tested.

Incorrect:  The hypotheses was tested.

Using the correct verb agreement is just as important as using the correct plural form.

Plural Noun Rules For Regular Nouns

When it comes to making nouns plural, there are a few rules that you should keep in mind. In this section, we’ll cover the rules for both regular and irregular nouns.

• Most regular nouns form their plurals by adding -s to the end of the singular form. For example, “car” becomes “cars”, “book” becomes “books”, and “desk” becomes “desks”.
• If the singular noun ends in -s, -x, -z, -ch, or -sh, add -es to the end to form the plural. For example, “box” becomes “boxes”, “buzz” becomes “buzzes”, “wish” becomes “wishes”, and “church” becomes “churches”.
• 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 “party” becomes “parties”.
• If the singular noun ends in a vowel followed by -y, add -s to form the plural. For example, “key” becomes “keys”, “boy” becomes “boys”, and “day” becomes “days”.
• If the singular noun ends in -f or -fe, change the -f or -fe to -ves to form the plural. For example, “knife” becomes “knives”, “life” becomes “lives”, and “leaf” becomes “leaves”.
• If the singular noun ends in a consonant followed by -o, add -es to form the plural. For example, “potato” becomes “potatoes”, “hero” becomes “heroes”, and “tomato” becomes “tomatoes”.
• If the singular noun ends in a vowel followed by -o, add -s to form the plural. For example, “studio” becomes “studios”, “zoo” becomes “zoos”, and “radio” becomes “radios”.

Remember, these are just the basic plural noun rules for regular nouns. There are always exceptions and irregular nouns that follow different rules for forming plurals.

Plural Noun Rules For Irregular Nouns

List of common irregular plural nouns.

Here is a list of some of the most common irregular plural nouns in English:

Remember, when it comes to making nouns plural, it’s important to follow the rules for each individual noun. By keeping these rules in mind, you’ll be able to make any noun plural with ease.

Nouns That End in Us

Nouns that end in “us” in their singular form usually have “i” added to the end to form the plural. For example:

• Plural: cacti
• Plural: fungi
• Plural: nuclei

Nouns  That End in Is

Nouns that end in “is” in their singular form usually have “es” added to the end to form the plural. For example:

• Plural: bases
• Plural: analyses
• Plural: hypotheses

Nouns That End in On and Um

Nouns that end in “on” or “um” in their singular form usually have “a” added to the end to form the plural. For example:

• Plural: criteria
• Plural: phenomena
• Plural: curricula

It’s important to note that there are many exceptions to these rules, and some nouns have irregular plural forms that don’t follow any specific pattern. However, by knowing these basic rules, you can form the plural of many nouns correctly.

Plurals That Are the Same as Singulars

Some words in English have the same form for both singular and plural. These are known as “singularia tantum” or “pluralia tantum” words. “Hypothesis” is not one of them, but it is important to be aware of these types of words.

Here are some examples of singularia tantum words:

These words do not have a separate plural form, and they are always used in their singular form, even when referring to multiple items.

It’s important to remember that these words do not follow the usual rules of English grammar, and they can be confusing for non-native speakers.

In contrast, “hypothesis” follows the usual rules of English grammar and has a separate plural form, “hypotheses.” It’s important to use the correct plural form when referring to multiple hypotheses in academic or scientific writing.

Words That Look Like Plural Nouns but Are Singular Nouns

In the English language, there are several words that look like they are plural nouns, but they are actually singular nouns. These words can be quite confusing, especially when it comes to using them in sentences. Here are some examples of such words:

• Mathematics
• Linguistics

It’s important to keep in mind that using these words correctly can help you sound more knowledgeable and confident in your writing. So, take some time to review the proper usage of these words and make sure you are using them correctly in your writing.

What Is The Definition Of Hypothesis

As found in the Meriam Webster Dictionary 

• An assumption or concession made for the sake of argument
• an interpretation of a practical situation or condition taken as the ground for action
• a tentative assumption made in order to draw out and test its logical or empirical consequences
• the antecedent clause of a conditional statement

As found in the Cambridge Dictionary

• an idea or explanation for something that is based on known facts but has not yet been proved: several hypotheses for global warming have been suggested.

In “The Origin of Hypothesis” it is phrased as a ‘scientific guess’. In the context of science, a hypothesis is a placeholder for a theory until it is proven by science to be accurate.

A scientific hypothesis sed to explain something occurring in our universe that currently does not fit into our current available scientific theories. Scientific hypotheses also include null hypothesis, working hypothesis, and alternative hypothesis. 

History and Origin of The Word

From the Greek hypotithenai to put under, suppose, from hypo- + tithenai to put. The first use of the word hypothesis can be traced back to 1596. Issac Newton actually rejected the hypothesis, he said “Hypotheses non fingo” which translates to “I Frame no hypotheses”. This was back in 1721 in Issac Newton’s book “Opticks, or A Treatise of the Reflections, Refractions, Inflections, and Colours of Light”

What Is More Than One Hypothesis Called?

The plural form of the hypothesis is hypotheses. This is the only way in the English language to make hypothesis plural. Because of the Greek origin, the rule of making a noun that ends in “is” to change it to “es.”

• Assumption – Something taken for granted
• Postulate- suggest or assume the existence, fact, or truth of (something) as a basis for reasoning, discussion, or belief
• Rationale – Logic for belief, action
• Previous observations- things that were seen or experienced in the past
• Supposition – guess, belief
• Theorem – explanation based on hypothesis and experiments done by experimenters using the scientific method
• Thesis – belief, assumption to be tested
• Conjecture – speculation, assumption
• Conclusion – end
• Tentative Explanation – clarification; reason
• Guess – belief, speculation 
• Interpretation – understanding
• Premise – hypothesis, argument

What Is The Difference Between Hypothesis and Theory?

Since we now know that a hypothesis is a guess or assumption, how is that different from a theory? The definition of a theory is “a supposition or system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained”. 

Although we might think of a theory as something that has not been 100% proven, its definition in the application of science is something that has been tested as an explanation for things occurring. It is still an explanation that is thought of as true until proven otherwise, the difference here is that a hypothesis is thought to explain something not yet tested and could also be thought of as an unproved theory or suggested explanation.

Follow these examples to see the difference in action:

• Fact: “The clouds are dark outside.” 
• Hypothesis: “It might storm today.”
• Theory: “Rain clouds are dark because of their particulate density. The denser the water droplets are in the cloud the more light will be scattered, which will lead to a darker appearance.”
• Fact: “Light roast coffee has more caffeine than dark roast coffee”
• Hypothesis: “I should drink a cup of light roast coffee if I want more caffeine”
• Theory: “During the roasting process caffeine is slowly burned off, therefore it is true that light roast coffee has more caffeine. You should however choose dark roast if you want more caffeine per cup because although per bean light roast has more caffeine, per gram of coffee dark roast contains more caffeine. This is because you have to consider the percent of weight loss that occurs with roasting a coffee to a dark level, which is higher than the percent of caffeine lost, therefore you have more caffeine per gram in dark roast over light roast, only by a minuscule amount.”

What Is The Difference Between An Idea and Hypothesis?

Since a hypothesis is an idea that can be tested, here are some examples of what is just an idea and can’t be tested followed by a similar idea that can be tested and is a hypothesis.

• Idea: Biden would be a better president vs Trump – Can not be tested since we have no data. 
• Hypothesis: Obama did a better job at fixing unemployment vs Bush – can be tested by looking at the data.
• Idea: I could have been the best disc golfer if I started playing when I was a kid – Impossible to test
• Hypothesis: Paul McBeth probably hit more circle 2 putts on tour last year than Ricky Wysocki. – Can be proven by looking at the data for all their putts on the PDGA tour last year.

Example Sentences In Context

The following are examples of hypothesis in context:

“We came up with the assumptions and then narrowed them down to one hypothesis for each category.” – Forbes

“The notion of hypothesis testing has recently invaded the practice of entrepreneurship as a tool to construct of new ventures” – Forbes

“There’s not one unifying hypothesis as to why, but there’s probably five to 20 different things that have contributed to it.” – USA Today

“Most thinkers or hypothesists of any degree of sobriety allow, that an hypothesis…is not to be received as probably true because it accounts for all the known phenomena since this is a condition sometimes fulfilled tolerably well by two conflicting hypotheses…while there are probably a thousand more which are equally possible, but which, for want of anything analogous in our experience, our minds are unfitted to conceive” – Underdetermination of Scientific Theory

“The expensive tissue hypothesis was focused on human brains and it was never intended as a one-size-fits-all possible explanation that applied across all mammals. The original paper even said that “the cost of the additional brain tissue could have been met by strategies other than a reduction in gut size.” – National Geographic

[But t]he word " hypothesis " should be used, in science, exclusively for a reasoned, sensible, knowledge-informed explanation for why some phenomenon exists or occurs. An hypothesis can be as yet untested; can have already been tested; may have been falsified; may have not yet been falsified, although tested; or may have been tested in a myriad of ways countless times without being falsified; and it may come to be universally accepted by the scientific community. An understanding of the word " hypothesis ," as used in science, requires a grasp of the principles underlying Occam's Razor and Karl Popper's thought in regard to " falsifiability "—including the notion that any respectable scientific hypothesis must, in principle, be "capable of" being proven wrong (if it should, in fact, just happen to be wrong), but none can ever be proved to be true. One aspect of a proper understanding of the word " hypothesis ," as used in science, is that only a vanishingly small percentage of hypotheses could ever potentially become a theory.

Whats the Plural of Hypothesis: Understanding Grammatical Number

• The word “hypotheses” is the plural form of “hypothesis.”
• “Hypothesis” and “hypotheses” are used to propose explanations for phenomena, with usage depending on the number.
• The origin of “hypothesis” traces back to Greek, affecting its pluralization in English.

In the most straightforward terms, the plural of “hypothesis” is “hypotheses.” This transformation follows a specific pattern seen in words that end in “-is,” with the “-is” changing to “-es” to form the plural. Understanding the correct use of the singular and plural forms is fundamental for both written and spoken English, especially within academic and scientific contexts where the word is frequently employed.

Table of Contents

What’s the Plural of “Hypothesis”?

Singular to Plural Transformation

The transformation from singular to plural for the word “hypothesis” involves altering the ending of the word:

• Change the “is” to “es”
• This results in the plural form “hypotheses”

Pronunciation

The plural form is pronounced as “hī-ˈpä-thə-ˌsēz.” It’s essential to note that the difference is not just in spelling but also in pronunciation.

Usage of Hypothesis and Hypotheses

Here is a simple breakdown of when to use each form:

Examples in Sentences

• Singular : The scientist tested the hypothesis to see if it was valid.
• Plural : After many experiments, all the hypotheses were evaluated for accuracy.

What’s the Singular of Hypothesis?

The singular form of hypothesis is “hypothesis.” To assist in understanding, consider the following tables:

Another table illustrating the usage in a sentence:

Here are key points to remember about the term “hypothesis”:

• It is the singular form used when referring to one proposed explanation.
• A hypothesis can later become a theory if it is supported by substantial evidence.
• In the realm of science, it is a statement subject to verification or falsification through research.

Defining the Word “Hypothesis”

The term hypothesis originates from the Greek word meaning base or foundation . It is commonly understood as a starting point for scientific inquiry, a proposed explanation made on the basis of limited evidence as a starting point for further investigation. In its essence, a hypothesis is a tentative assumption designed to test its logical or empirical consequences.

In scientific reasoning, a hypothesis serves as a provisional idea whose merit requires evaluation. It is not just a wild guess, but an informed conjecture that sets the stage for experimentation and observation.

Key Attributes of a Hypothesis:

• Conjectural : A hypothesis is an educated guess about the relationship between two or more variables.
• Testable : It must be possible to prove that the hypothesis is true or false through evidence.
• Predictive : A hypothesis should make predictions that can be verified through testing.
• Falsifiable : To be scientific, a hypothesis must be structured in a way that it can be refuted by evidence.

Hypothesis in Conditional Statements:

For example, in the statement “If molecules are exposed to higher temperatures, then their kinetic energy will increase,” the hypothesis is that higher temperatures affect molecular kinetic energy.

Hypothesis (Singular) Used in Sentences

Examples in Sentences:

• The scientist formulated a hypothesis about the effect of light on plant growth.
• After analyzing the data, she presented her hypothesis concerning the animals’ migration patterns.
• His hypothesis that increased sunlight would enhance energy efficiency remains to be tested.
• In her thesis, the hypothesis revolved around the impact of social media on communication skills.
• It is key for a hypothesis to be clear and concise for it to lead to meaningful scientific investigation.

Regarding the use of “hypothesis” in academic writing, it is important to:

• Identify the key variable : Highlight what the hypothesis is specifically attempting to test or predict.
• State the expected outcome : Clarify the predicted result or effect that the hypothesis addresses.

Tips for crafting a hypothesis :

• Keep it simple and testable.
• Ensure it is backed by existing literature and theories when applicable.
• Tailor it to be specific , addressing a particular phenomenon or set of data.
• A hypothesis must be falsifiable ; that is, it must be phrased in a way that makes it possible to reject if it is not true.
• Avoid complex jargon when constructing a hypothesis; clarity ensures that others can understand and test it.
• Remember, a hypothesis is not a question, but rather a statement that reflects what the researcher believes to be true.

Hypotheses (Plural) Used in Sentences

In the realm of research, it’s common to encounter:

Example Sentences:

• The scientists reviewed several competing hypotheses before commencing their experiment.
• Their hypotheses centered on the potential effects of climate change on marine biodiversity.
• During the symposium, the researcher explained her methods for testing the various hypotheses .

Using “hypotheses” precisely:

• Clarity : Each of the hypotheses represented a possible explanation for the phenomenon observed.
• Context : In scientific discussions, it’s paramount to present hypotheses in a structured manner.
• Comparison : The study contrasted traditional hypotheses with innovative conjectures emerging in the field.

In day-to-day language or teaching scenarios, one might encounter scenarios such as:

• The teacher asked the students to write down their own hypotheses about the outcome of the chemical reaction.
• The book included several interesting hypotheses about the origins of language.

Origin of the Word “Hypothesis”

Ancient Greek is the initial source of the word “hypothesis.” Specifically, it derives from two Greek words: “ὑπό” meaning ‘under,’ and “θέσις” meaning ‘a placing’ or ‘proposition.’ The combination of these elements resulted in “ὑπόθεσις” (hypothesis), signifying ‘a placing under’ or ‘foundation’.

Transitioning into Late Latin , the term “ hypothesis ” maintained its original Greek meaning. By the time it reached the Middle French , as “hypothese,” it was already well-incorporated into the lexicon of scientific and philosophical discourse.

In English, “hypothesis” retains the essence of its Greek origins: a proposed explanation for a phenomenon, a foundation for further investigation, or a premise to be tested.

Key Developments :

• Integral to scientific method
• Used academically to propose theories

To construct the plural form of “hypothesis,” English follows a standard pattern seen with words ending in ‘-is.’

• Singular: hypothesis
• Plural: hypotheses

Usage in English implies not just a simple carrying over of a term, but an adaptation of the concept it represents — underpinning the advancement of knowledge, it supports theoretical frameworks and empirical research.

Related Words explanation interpretation proposition supposition More About Hypothesis What is a hypothesis . In science, a hypothesis is a statement or proposition that attempts to explain phenomena or facts. Hypotheses are often tested to see if they are accurate. Crafting a useful hypothesis is one of the early steps in the scientific method , which is central to every field of scientific experimentation. A useful scientific hypothesis is based on current, accepted scientific knowledge and is testable. Outside of science, the word hypothesis is often used more loosely to mean a guess or prediction. Why is hypothesis important? The first records of the term hypothesis come from around 1590. It comes from the Greek term hypóthesis , meaning “basis, supposition.” Trustworthy science involves experiments and tests. In order to have an experiment, you need to test something. In science, that something is called a hypothesis . It is important to remember that, in science, a verified hypothesis is not actually confirmed to be an absolute truth. Instead, it is accepted to be accurate according to modern knowledge. Science always allows for the possibility that new information could disprove a widely accepted hypothesis . Related to this, scientists will usually only propose a new hypothesis when new information is discovered because there is no reason to test something that is already accepted as scientifically accurate. Did you know … ? It can take a long time and even the discovery of new technology to confirm that a hypothesis is accurate.

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.

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.” Words and phrases Personal account.
