The easiest way to remember when to use am, is, and are is to match the verb to the subject of the sentence. Use am exclusively with I. Use is for any single person or thing (he, she, it). Use are for you and any plural subject (we, they, the dogs).
Learning English grammar can feel overwhelming, but some rules are simpler than they seem. A common hurdle for beginners is mastering the present tense forms of the verb 'to be': am, is, and are. Getting this right is fundamental to building clear, correct sentences. The good news is that there’s a very simple trick for a beginner to remember when to use am, is, and are correctly every time. It’s all about identifying the subject!
How Do I Remember When to Use Am, Is, and Are?
The secret is subject-verb agreement. This just means the subject (who or what the sentence is about) and the verb (the action or state of being) must match. For 'am,' 'is,' and 'are,' the rules are very clear.
The 'I Am' Rule: Your Personal Verb
This is the simplest rule of all. The word am is a special verb that is only ever used with the pronoun I.
- I am a student.
- I am feeling happy today.
- I am from Brazil.
You will never use 'am' with any other subject. Think of 'am' as your own personal verb.
The 'Is' Rule: For Singular Subjects
The verb is is used when the subject of your sentence is singular. This means it's about one person, one place, one thing, or one idea. This includes the pronouns he, she, and it.
- He is a teacher.
- She is my sister.
- It is a beautiful day.
It also applies to any singular noun:
- The dog is sleeping.
- My house is blue.
- Sarah is at the library.
If you're talking about just one thing, the correct verb is 'is'.
The 'Are' Rule: For 'You' and Plural Subjects
The verb are pulls double duty. It's used for plural subjects (more than one) and it's *always* used with the pronoun you, even when 'you' refers to just one person.
Let’s look at the pronouns we and they, which are always plural:
- We are ready for the exam.
- They are my friends.
It also applies to any plural noun:
- The dogs are playing in the park.
- My books are on the table.
- Sarah and Tom are at the library.
And remember the special case for you:
- You are a great student. (Speaking to one person)
- You are all great students. (Speaking to many people)

What About Using 'Am, Is, Are' in Questions and Negative Sentences?
Once you've mastered the basic rule, applying it to questions and negative statements is easy.
For questions, simply move the verb (am, is, or are) to the beginning of the sentence, before the subject.
- Am I in the right class?
- Is she your friend?
- Are they from Canada?
For negative sentences, just add the word 'not' after the verb.
- I am not tired.
- He is not (isn't) a doctor.
- We are not (aren't) late.
Mastering subject-verb agreement is a huge step in your English journey. By focusing on matching the subject to the verb, you now have a foolproof method to remember when to use am, is, and are. Keep practicing, and soon it will become second nature!
Frequently Asked Questions (FAQ)
Q: Why do we use 'are' with 'you' even for one person?
A: This is a great question that shows how English has evolved. Historically, 'you' was only used for plural or formal situations (like 'vous' in French). Over time, it replaced the singular form ('thou'), but it kept its plural verb, 'are'. So today, we use 'you are' for both one person and multiple people.
Q: Can I use 'is' for a group of people, like 'the team is'?
A: Yes, you can. This is a concept called 'collective nouns.' A noun like 'team,' 'family,' 'group,' or 'committee' refers to a group of individuals but is treated as a single unit. In American English, it's most common to treat these as singular: "The team is playing well." In British English, it can be either singular or plural, depending on context.
Q: What is the past tense of am, is, and are?
A: The past tense forms of the verb 'to be' are 'was' and 'were.' 'Was' is the past tense for 'am' and 'is' (I was, he was, she was, it was). 'Were' is the past tense for 'are' (you were, we were, they were).
Q: How do I make contractions with am, is, and are?
A: Contractions are shortened forms used in informal speech and writing.
- I am → I'm
- He is / She is / It is → He's / She's / It's
- You are / We are / They are → You're / We're / They're
- Is not → Isn't
- Are not → Aren't
- Note: 'Am not' does not have a common contraction, though 'ain't' is used in some informal dialects.
