When choosing between behaviours or behaviors, the correct spelling depends on the type of English you are using. “Behaviors” is the standard American English spelling, while “behaviours” is the standard British English spelling. Both forms have the same meaning and refer to the ways people, animals, or groups act and respond.
This spelling difference is common because American and British English often use slightly different endings. Words such as color/colour, favorite/favourite, and behavior/behaviour follow this pattern. If you are writing for a U.S. audience, school, workplace, website, or American publication, behaviors is usually the form you should choose.
In this guide, you will learn the meaning of the word, the difference between the two spellings, how to use it in sentences, common mistakes, and simple ways to remember which form belongs in American English.
Quick Answer: Behaviours or Behaviors?
The quick answer is simple: “behaviors” is the correct spelling in American English, while “behaviours” is the British English spelling.
Both words have the same meaning. They describe actions, reactions, habits, or ways of acting. The only difference is the spelling.
| Spelling | Main English Variety | Example |
| behaviors | American English | Children learn behaviors from people around them. |
| behaviours | British English | Children learn behaviours from people around them. |
If you are writing an article for readers in the United States, use behaviors. If you are writing for readers in the United Kingdom, behaviours is generally preferred.
The same difference appears in the singular form. American English uses behavior, while British English normally uses behaviour.
Meaning and Definition of Behavior
Behavior means the way a person, animal, or group acts or responds in a particular situation. It can describe actions that are easy to see, such as smiling, shouting, helping, or running. It can also describe patterns of action, such as spending habits, eating habits, or social behavior.
For example, if a child shares a toy with another child, that action can be described as kind behavior. If a dog barks whenever someone approaches the door, that action is also a form of behavior.
The plural form, behaviors, is used when talking about more than one type or example of behavior.
For example:
“Children can develop healthy behaviors through good examples.”
The sentence refers to several possible actions or habits, not just one.
Behavior is a broad word, so it can appear in many areas. Teachers may talk about student behavior. Doctors and researchers may discuss human behavior. Animal experts may study animal behavior. Businesses may examine consumer behaviors to understand how customers make choices.
Why Are Behaviors and Behaviours Spelled Differently?
The difference comes from the spelling traditions of American and British English.
American English generally uses behavior, while British English uses behaviour. The same pattern continues when the word becomes plural:
behavior → behaviors
behaviour → behaviours
There is no major difference in meaning. The spelling changes because English developed different writing conventions in different regions.
American English often removes the letter u from words that end in -our in British English. This can be seen in several familiar pairs.
| American English | British English |
| behavior | behaviour |
| color | colour |
| favor | favour |
| honor | honour |
| labor | labour |
| neighbor | neighbour |
This does not mean one spelling is universally correct and the other is wrong. Instead, the preferred spelling depends on the English variety being used.
For a U.S.-focused website, behaviors is the natural choice.
Grammar and Correct Usage
The word behaviors is the plural form of the noun behavior in American English.
You can use behavior when discussing one type, pattern, or general concept. You can use behaviors when referring to multiple actions, habits, or patterns.
For example:
“His behavior was unusual.”
Here, the writer is talking about a general pattern of action.
Now consider:
“His behaviors changed after he started working from home.”
Here, the writer is referring to multiple actions or habits.
The word can also appear with descriptive adjectives.
Examples include:
healthy behaviors
social behaviors
positive behaviors
negative behaviors
learning behaviors
consumer behaviors
workplace behaviors
animal behaviors
online behaviors
These phrases are common because they help explain the specific type of action being discussed.
One important point is that behavior can also be used as a general, uncountable noun. For example:
“Good behavior is important in the classroom.”
In this sentence, behavior describes a general idea rather than separate actions.
Real-Life Examples of Behaviors
Understanding the word becomes easier when you see it in everyday sentences.
Parents may talk about children’s behaviors when describing how children act at home or school. A teacher might discuss positive behaviors that help students learn. A manager may notice different workplace behaviors among employees.
Here are some examples:
“Positive behaviors can make a classroom more comfortable.”
“Some animals change their behaviors when the weather changes.”
“Parents often teach children healthy behaviors.”
“Social behaviors can vary between cultures.”
“Online behaviors can affect how people communicate.”
“Customers have different shopping behaviors.”
“Healthy eating behaviors can become daily habits.”
“Some workplace behaviors can improve teamwork.”
The word can describe good, bad, neutral, expected, or unusual actions. The meaning depends on the surrounding sentence.
For example, positive behaviors suggests helpful actions, while negative behaviors suggests actions that may cause problems.
Behaviors in Everyday Life
People display behaviors throughout the day, often without thinking about them.
Getting ready for work, greeting someone, checking a phone, helping a friend, exercising, eating, and responding to a stressful situation are all examples of human behavior.
Some behaviors are learned. Others may be influenced by surroundings, habits, social expectations, personal experiences, or many other factors.
For example, a child may learn to say “please” and “thank you” from parents or teachers. A new employee may learn workplace behaviors by observing coworkers.
Behavior can also change over time. Someone might develop a new habit, change the way they communicate, or respond differently to a familiar situation.
This is why the word appears in many everyday discussions. It gives people a simple way to describe actions and patterns without needing a separate word for every type of action.
Behaviors in Science and Psychology
The word behaviors is also common in scientific and academic writing.
In psychology, researchers may study human behaviors to better understand how people act in different situations. In biology, scientists may study animal behaviors, such as feeding, communication, movement, or social interaction.
The word is useful because it describes observable actions without necessarily explaining why those actions happen.
For example:
“Researchers observed changes in the animals’ behaviors.”
This sentence tells readers that researchers noticed changes in how the animals acted. It does not automatically explain the cause of those changes.
That distinction is important in careful writing. A behavior can be observed, while the reason behind it may require additional evidence.
Behaviors in School and the Workplace
Behavior is a common topic in education.
Teachers may use phrases such as positive behaviors, classroom behaviors, or learning behaviors when describing how students act during lessons.
For example:
“Teachers encourage positive behaviors that support learning.”
In the workplace, people may discuss professional behaviors, workplace behaviors, or communication behaviors.
For example:
“Professional behaviors can help create a respectful workplace.”
These phrases describe actions such as listening, communicating clearly, arriving on time, cooperating with others, and following workplace rules.
The exact meaning depends on the context, so writers should provide enough information for readers to understand which actions they mean.
American English vs. British English
The most important spelling difference is the extra u in the British form.
American English:
behavior
behaviors
British English:
behaviour
behaviours
Both forms are accepted within their respective varieties of English.
If your audience is mainly American, consistency matters. Using behaviors throughout your article will make your writing fit standard American spelling.
If you are writing for a British audience, use behaviours.
Canadian, Australian, and other English varieties may follow British-style spelling in many cases, but regional spelling preferences can vary. When writing for a specific audience, it is useful to follow the spelling style expected by that publication, school, organization, or country.
Common Mistakes With Behaviours or Behaviors
One common mistake is treating behaviours as incorrect everywhere. It is not incorrect. It is the standard British spelling.
Another mistake is using both forms randomly in the same American English article.
For example, a U.S.-focused article might use “behaviors” in one paragraph and “behaviours” in another. This creates an inconsistent spelling style.
A better approach is to choose one variety of English and stay consistent.
Another mistake is assuming that the extra u changes the pronunciation or meaning. In normal use, the spelling difference does not create a different meaning.
Writers should also avoid using the plural form when they are discussing behavior as a general concept.
For example:
“Good behavior is important.”
This is more natural than:
“Good behaviors is important.”
If you mean several specific actions, then the plural form works:
“Good behaviors can help create a positive classroom.”
The key is to match the noun form with the meaning of the sentence.
Common Spelling and Grammar Mistakes
| Mistake | Better Form | Why |
| behaviours in a U.S. article | behaviors | Use American spelling for a U.S. audience. |
| behaviors is important | behavior is important | Use singular behavior for a general concept. |
| behavior are changing | behaviors are changing | Use the plural form with “are.” |
| one behaviors | one behavior | A singular subject needs the singular noun. |
| many behavior | many behaviors | A plural quantity needs the plural noun. |
Another useful rule is to check the words around behavior.
If the sentence says “this behavior,” the singular form is needed.
If it says “these behaviors,” the plural form is needed.
This simple check can prevent many grammar errors.
How to Remember the Correct American Spelling
A simple way to remember the American spelling is to focus on the missing u.
American English:
behavior
British English:
behaviour
Think of behavior as the shorter American form.
You can use the same memory trick with other words:
color → colour
favor → favour
honor → honour
neighbor → neighbour
When writing for an American audience, many of these words use the shorter -or spelling rather than the British -our spelling.
However, not every English word follows exactly the same pattern, so it is better to check unfamiliar words rather than apply the rule automatically.
When Should You Use Behaviors?
Use behaviors when your sentence refers to two or more actions, habits, or patterns and you are writing in American English.
For example:
“Healthy behaviors can improve daily routines.”
“Children develop social behaviors as they interact with others.”
“Researchers studied the behaviors of several animal species.”
“Positive workplace behaviors can support teamwork.”
“Online behaviors have changed as technology has developed.”
If you are talking about one general concept, use behavior instead:
“Good behavior matters.”
“His behavior surprised everyone.”
“Animal behavior can be complex.”
The choice between singular and plural is therefore separate from the choice between American and British spelling.
When Should You Use Behaviours?
Use behaviours when writing in British English or another variety that follows the British spelling convention.
For example:
“Children learn behaviours from people around them.”
“Researchers observed different animal behaviours.”
“Positive behaviours can improve classroom relationships.”
The meaning is exactly the same as the American versions.
If you are writing an academic paper, website, business document, or school assignment, follow the spelling style required by your audience or institution.
Consistency is more important than switching between forms without a reason.
Behaviors vs. Behaviour: Singular and Plural Forms
The singular and plural forms can sometimes cause confusion because there are actually two spelling systems involved.
| Meaning | American English | British English |
| One general pattern or action | behavior | behaviour |
| More than one pattern or action | behaviors | behaviours |
For example:
American: “The student’s behavior improved.”
British: “The student’s behaviour improved.”
American: “The students showed positive behaviors.”
British: “The students showed positive behaviours.”
The meaning remains the same. Only the spelling convention changes.
This distinction is especially helpful when editing articles, essays, or professional documents.
Current Usage and Writing Style
In modern American English, behavior and behaviors are widely used in education, business, psychology, science, health writing, and everyday communication.
The plural form is particularly useful when writers want to describe several observable actions or habits.
For SEO content aimed at American readers, the spelling behaviors is generally the natural choice when the word is being used as a plural noun.
However, search engines can understand related spellings and language variations. Writers should not force the keyword into every sentence. Clear, natural writing is more important than repeating the same phrase.
If your website targets several countries, you can explain the spelling difference once and then follow the style of the audience you are writing for.
Tips for Using Behaviors Correctly
First, identify your audience. If you are writing for readers in the United States, choose behavior and behaviors.
Second, decide whether you mean one general concept or multiple actions. Use behavior for the singular form and behaviors for the plural form.
Third, stay consistent. Avoid changing between American and British spelling without a clear reason.
Fourth, read the complete sentence. Words such as this, that, these, and those can help you identify whether the noun should be singular or plural.
Finally, use a dictionary or style guide when you are unsure. This is especially helpful when writing formal academic or professional content.
