Mastering subject-verb agreement is one of the most important aspects of English grammar, and it often comes down to knowing when to use “is” and when to use “are.” Both words are forms of the verb “to be”, but their correct usage depends on the subject-verb agreement rules. Understanding this concept is crucial for writing and speaking clearly, whether in academic writing, professional communication, or everyday conversation.
The word “is” is typically used with singular nouns and pronouns, while “are” pairs with plural nouns and pronouns. For example, we say “She is happy” but “They are happy.” This may sound simple, but many learners struggle with tricky cases such as collective nouns, compound subjects, or indefinite pronouns where the choice between “is” and “are” is not immediately obvious.
In this guide, we will break down the rules of subject-verb agreement, provide clear examples, and highlight common mistakes so you can confidently decide whether to use “is” or “are” in any sentence. By the end, you will not only avoid grammar errors but also improve your English fluency and overall communication skills.
The Core Rule of “Is” and “Are”
At the heart of the issue lies subject–verb agreement. The verb must agree in number with the subject of the sentence.
- Singular subject → “is”
- Plural subject → “are”
Here’s a quick chart for the verb to be in the present tense:
Subject | Correct Verb | Example |
I | am | I am happy. |
You | are | You are smart. |
He/She/It | is | She is kind. |
We | are | We are ready. |
They | are | They are late. |
So, when you decide between is and are, ask: Is my subject singular or plural? That’s the key starting point.
Using “Is” Correctly
Singular Nouns and Pronouns
When the subject is one person, object, or idea, the verb takes is.
- The book is on the table.
- She is my best friend.
- My dog is playful.
Abstract and Uncountable Nouns
Uncountable or mass nouns take is because they represent a single concept.
- Happiness is priceless.
- Water is essential for life.
- Information is power.
Singular Collective Nouns
Collective nouns can cause confusion. If the group is seen as one unit, use is.
- The team is winning.
- The family is large.

Examples in Real Sentences

- “The news is surprising.”
- “The orchestra is rehearsing for tomorrow’s concert.”
Using “Are” Correctly
Plural Nouns and Pronouns
When the subject refers to more than one, use are.

Plural Collective Nouns
When the group is viewed as individual members, use are.

Indefinite Pronouns
Some indefinite pronouns are singular (everyone, each, anybody). Others are plural (many, few, several).
- Everyone is welcome.
- Few are missing.
- Many are waiting.
Titles, Names, and Organizations
Titles, names of books, movies, countries, or organizations are treated as singular, even if they look plural.
- “The United States is a diverse country.”
- “‘Friends’ is a popular sitcom.”
- “The United Nations is headquartered in New York.”
Fractions and Percentages
The verb agrees with the noun that follows.
- Two-thirds of the cake is gone.
- Two-thirds of the people are here.
- Fifty percent of the money is missing.
“There Is” vs. “There Are”
Introducing Sentences with “There”
Sentences beginning with “there” use a dummy subject, which means the verb agrees with the real subject that comes after.

- There are books on the desk.
Common Mistakes
Many people mistakenly use “there’s” with plurals in casual speech. While common, it’s grammatically incorrect.
