Is vs Are: How to Use Them Correctly

Choosing between is and are seems simple at first, but these two small words cause more grammar mistakes than many people realize. Whether you’re writing an email, completing schoolwork, creating business content, or improving your English skills, using the correct verb helps your writing sound natural and professional. Since is and are are both present-tense forms of the verb to be, selecting the right one depends on understanding the subject of your sentence.

Many learners memorize a few basic rules, yet they still get confused by collective nouns, long sentences, indefinite pronouns, or phrases like there is and there are. Even native English speakers occasionally make mistakes, especially in casual conversation. Fortunately, subject-verb agreement follows predictable patterns that become much easier once you know what to look for.

This guide explains is vs. are in simple language with clear rules, comparison tables, practical examples, and common mistakes to avoid. By the end, you’ll know exactly when to use is, when to use are, and how to recognize tricky situations that often confuse writers.

Quick Answer: Is It “Is” or “Are”?

The Simple Rule

The easiest way to choose between is and are is to identify the subject of the sentence.

• Use is with singular subjects.
• Use are with plural subjects.

Examples:

• The dog is sleeping.
• The dogs are sleeping.

How to Decide in Seconds

Ask yourself one simple question:

Is the subject one person, place, thing, or idea?

• If the answer is yes, use is.
• If the answer is more than one, use are.

Quick Comparison Table

Subject Type	Correct Verb	Example
Singular noun	Is	The book is interesting.
Plural noun	Are	The books are interesting.
He, She, It	Is	She is happy.
We, They, You	Are	They are ready.
Uncountable noun	Is	Water is important.

What Are “Is” and “Are”?

Understanding the Verb “To Be”

The verb to be is one of the most important verbs in English. It connects the subject to information about that subject.

Examples:

• She is a teacher.
• They are students.
• The weather is beautiful.
• My friends are here.

Without the correct form of to be, many English sentences become grammatically incorrect.

Present-Tense Forms of “To Be”

Here’s how the verb changes.

Subject	Present-Tense Verb
I	Am
You	Are
He	Is
She	Is
It	Is
We	Are
They	Are

Notice that am only works with I, while is and are depend on whether the subject is singular or plural.

Why Subject-Verb Agreement Matters

Subject-verb agreement means the verb must match the subject in number.

Correct:

• The student is studying.
• The students are studying.

Incorrect:

• The student are studying.
• The students is studying.

Matching the subject correctly improves clarity and makes your writing sound polished.

The Basic Rule of Subject-Verb Agreement

Singular Subjects Take “Is”

Whenever your subject refers to one person, animal, object, or idea, use is.

Examples:

• My brother is a doctor.
• The computer is new.
• Her idea is brilliant.
• The cat is asleep.

Plural Subjects Take “Are”

When your subject refers to more than one, use are.

Examples:

• My brothers are doctors.
• The computers are new.
• Their ideas are creative.
• The cats are sleeping.

Why This Rule Is Essential

This single rule forms the foundation of English grammar.

Once you recognize whether the subject is singular or plural, choosing the correct verb becomes much easier.

When to Use Is

Singular Nouns

A singular noun names one person, place, thing, or concept.

Examples:

• The restaurant is busy.
• My phone is charging.
• The meeting is tomorrow.
• The answer is correct.

Singular Pronouns

Several pronouns always take is.

These include:

• He
• She
• It
• This
• That

Examples:

• He is excited.
• She is confident.
• It is raining.
• This is delicious.
• That is impossible.

Uncountable (Mass) Nouns

Some nouns cannot normally be counted individually.

These usually take is.

Examples include:

• Water
• Milk
• Furniture
• Advice
• Information
• Equipment
• Money
• Homework
• Traffic

Example sentences:

• Water is essential for life.
• Furniture is expensive.
• Information is available online.
• Advice is always appreciated.

Although these nouns may represent many individual items, English treats them as singular.

Singular Indefinite Pronouns

Several indefinite pronouns always take is, even when they seem to refer to multiple people.

Examples:

• Everyone
• Someone
• Nobody
• Anybody
• Everyone
• Each
• Every

Correct usage:

• Everyone is welcome.
• Somebody is waiting outside.
• Each student is responsible for completing the assignment.
• Nobody is perfect.

These words often confuse learners because they refer to groups while remaining grammatically singular.

Example Sentences Using “Is”

• My laptop is working perfectly.
• The library is open today.
• Every employee is expected to attend.
• The weather is getting warmer.
• This book is worth reading.

When to Use Are

Plural Nouns

Plural nouns require are.

Examples:

• The children are playing.
• The flowers are blooming.
• My neighbors are friendly.
• The reports are finished.

Plural Pronouns

Use are with these pronouns:

• You
• We
• They
• These
• Those

Examples:

• You are welcome.
• We are ready.
• They are traveling.
• These are delicious.
• Those are expensive.

Compound Subjects Joined by “And”

When two singular subjects are connected by and, the subject becomes plural.

Examples:

• Sarah and David are friends.
• Coffee and tea are available.
• Reading and writing are important skills.

This is one of the easiest rules to remember because and usually signals more than one subject.

Example Sentences Using “Are”

• The employees are attending training.
• My parents are visiting next week.
• These shoes are comfortable.
• The mountains are beautiful.
• Your ideas are inspiring.

Is vs. Are: Side-by-Side Comparison

Situation	Use Is	Use Are
One person	✔	✘
More than one person	✘	✔
One object	✔	✘
Several objects	✘	✔
He, She, It	✔	✘
We, They, You	✘	✔
Uncountable nouns	✔	✘
Subjects joined by and	✘	✔

Subject Pronouns and the Correct Verb

Subject pronouns always follow the same pattern.

Subject	Correct Verb	Example
I	Am	I am happy.
You	Are	You are welcome.
He	Is	He is late.
She	Is	She is smiling.
It	Is	It is cold outside.
We	Are	We are excited.
They	Are	They are waiting.

A common mistake involves you.

Although you can refer to one person, English always pairs it with are.

Correct:

• You are my best friend.

Incorrect:

• You is my best friend.

Examples That Clearly Show the Difference

Everyday Conversation

• My coffee is hot.
• Your keys are on the table.
• The movie is starting soon.
• My friends are already inside.

School Examples

• The teacher is explaining the lesson.
• The students are taking notes.
• Each assignment is graded carefully.
• The classrooms are clean.

Workplace Examples

• The manager is available.
• The employees are working remotely.
• Every meeting is scheduled in advance.
• The reports are complete.

Business Writing Examples

Correct:

• The financial statements are available.
• Each department is responsible for its budget.

Academic Writing Examples

• The experiment is complete.
• The results are statistically significant.
• Every observation is recorded carefully.
• The researchers are analyzing the data.

Common Mistakes Beginners Make

Many grammar mistakes happen because writers focus on the wrong noun.

Consider this sentence:

The box of pencils is on the desk.

Some learners mistakenly choose are because they notice pencils.

However, the true subject is box, which is singular.

Likewise:

The list of names is complete.

The subject isn’t names. It’s list.

A good habit is to identify the main subject before choosing the verb. Ignore descriptive phrases that come between the subject and the verb. This simple strategy will eliminate many common is vs. are errors.

FAQs

When should I use is in a sentence?

Use is with singular subjects, including singular nouns, singular pronouns (he, she, it), and most uncountable nouns. For example:

• The dog is friendly.
• She is a doctor.
• Water is essential for life.

If the subject refers to one person, place, thing, or idea, is is usually the correct choice.

When should I use are in a sentence?

Use are with plural subjects and the pronouns you, we, and they. It also follows compound subjects joined by and.

Examples:

• The children are playing outside.
• We are ready to begin.
• Sarah and Tom are classmates.

Whenever the subject refers to more than one person or thing, are is generally the correct verb.

Why does you always take are?

Although you can refer to one person or many people, modern English always pairs it with are. This rule developed from the historical use of you as both a singular polite form and a plural pronoun.

Correct examples:

• You are welcome.
• You are my best friend.
• You are all invited.

Using you is is always incorrect in standard English.

Can collective nouns use both is and are?

Yes. Collective nouns can take is or are, depending on whether the group is acting as a single unit or as individual members.

Examples:

• The team is winning the championship. (The team acts as one unit.)
• The team are wearing different warm-up jackets. (British English often treats members individually.)

In American English, collective nouns usually take is, while British English may use are when emphasizing individual members.

What is the difference between there is and there are?

Use there is before a singular noun and there are before a plural noun.

Examples:

• There is a book on the table.
• There are three books on the table.

The verb always agrees with the noun that follows it.

Why does the number of take is, but a number of takes are?

This is one of the most confusing grammar rules.

• The number of refers to a single quantity, so it takes is.
• A number of means several, so it takes are.

Examples:

• The number of applicants is increasing.
• A number of applicants are waiting outside.

Is none singular or plural?

None can be singular or plural depending on what it refers to.

Examples:

• None of the information is missing. (Information is uncountable.)
• None of the students are absent. (Students are plural.)

Both forms are accepted when they match the intended meaning.

Why do uncountable nouns take is?

Uncountable nouns represent things that English treats as a single whole rather than individual items. Because of this, they usually take is.

Common examples include:

• Water
• Advice
• Furniture
• Equipment
• Information
• Homework
• Knowledge
• Traffic

Example sentences:

• Advice is valuable.
• Furniture is expensive.

What are the most common is vs. are mistakes?

Some of the most frequent mistakes include:

• Matching the verb to the wrong noun.
• Forgetting that you always takes are.
• Using are with uncountable nouns.
• Mixing there is and there are.
• Misusing collective nouns.
• Confusing the number of with a number of.

Carefully identifying the subject before choosing the verb helps eliminate most of these errors.

How can I improve my subject-verb agreement?

The best way to improve is through consistent practice and careful proofreading.

Here are a few simple tips:

• Identify the true subject before choosing the verb.
• Ignore extra words between the subject and the verb.
• Read your sentences aloud to check if they sound natural.
• Practice with everyday examples from books, articles, and conversations.
• Review common grammar exceptions regularly.

The more you read and write, the easier it becomes to recognize whether is or are is the correct choice.

Conclusion

Understanding the difference between is and are is one of the most important steps toward mastering English grammar. Although the rule seems simple, many writers make mistakes when dealing with collective nouns, uncountable nouns, compound subjects, and expressions like there is and there are. Learning how subject-verb agreement works helps you avoid these common errors and makes your writing clearer, more accurate, and more professional.

The easiest way to choose the correct verb is to identify the true subject of the sentence. If the subject is singular, use is. If the subject is plural, use are. While a few grammar rules and exceptions require extra attention, they become much easier to remember with regular reading, writing, and practice. Paying close attention to the subject instead of nearby words will help you make the right choice every time.

Whether you’re writing an email, completing school assignments, creating business documents, or improving your everyday English, using is and are correctly strengthens your communication skills. By applying the rules, examples, and tips covered in this guide, you’ll write with greater confidence and avoid many of the grammar mistakes that even experienced English speakers sometimes make.
