Master the Be Verb: Am, Is, and Are

The verb to be is the most important foundation in the English language, appearing in almost every conversation you will ever have. Whether you are introducing yourself, describing how you feel, or talking about where you live, you need this versatile verb. In this guide, we will break down exactly how to use am, is, and are with clarity and confidence.

What Is the "Be" Verb?

Unlike most English verbs that describe actions like running, eating, or studying, the be verb describes a state of being, identity, or condition. It acts like an equal sign in mathematics, connecting your subject to information about that subject.

Here are the three primary forms of the be verb in the simple present tense:

• Am
• Is
• Are

Your choice among these three words depends entirely on the subject of your sentence. Matching the subject to the correct verb form is called subject-verb agreement.

Choosing the Right Form: Subject Rules

To speak natural English without hesitation, you need to know which pronoun matches which verb form instantly. Let us look at each one in detail.

1. Using "Am"

The word am is the easiest to remember because it pairs with only one subject: the first-person singular pronoun I.

• I am a student.
• I am excited to learn English.
• I am twenty-four years old.
• I am at home right now.

In spoken and informal English, native speakers usually combine these words into a contraction: I'm (I'm happy to meet you).

2. Using "Is"

Use is whenever your subject is a singular third-person pronoun (he, she, it) or any single person, place, or thing.

• He is a talented musician. (He's a musician.)
• She is my English teacher. (She's my teacher.)
• It is cold outside today. (It's cold outside.)
• The coffee is hot.
• London is a large city.

Notice that singular nouns like the coffee or London can be replaced by the pronoun it, which is why they take is.

3. Using "Are"

Use are whenever your subject is you (singular or plural), we, they, or any plural noun.

• You are a wonderful friend. (You're a wonderful friend.)
• We are ready to order dinner. (We're ready.)
• They are walking in the park. (They're walking.)
• The books are on the shelf.
• Sarah and David are coworkers.

Even when you speak to just one person, you always takes are, never is.

Forming Negatives and Questions

Once you know positive statements, forming negative sentences and questions is straightforward.

Negative Sentences

To make a sentence negative, simply add the word not directly after the be verb.

• I am not tired. (I'm not tired.)
• He is not at work. (He isn't at work.)
• They are not ready. (They aren't ready.)

Notice the standard contractions for negatives: is not becomes isn't, and are not becomes aren't. Note that am not does not combine into a single word in standard English; you keep it as I'm not.

Questions

To ask a question, invert the order: put the be verb at the beginning of the sentence before the subject.

• Statement: You are tired. → Question: *Are you tired?*
• Statement: She is from Canada. → Question: *Is she from Canada?*
• Statement: They are ready. → Question: *Are they ready?*

For short answers, repeat the verb: "Yes, I am" or "No, she isn't."

Common Mistakes

Even intermediate learners occasionally slip up with the be verb. Watch out for these three frequent errors:

• Using the wrong form with "You": Never say "You is kind." Always remember that you requires are, whether speaking to one person or twenty: "You are kind."
• Confusing "they're", "their", and "there": Remember that they're means they are. Their shows possession (their house), and there indicates a place (over there).
• Omitting the be verb entirely: In some languages, the be verb is omitted in the present tense. In English, you must include it. Never say "She beautiful" or "I from Tokyo." Say "She is beautiful" and "I am from Tokyo."
• Double verbs with simple actions: Do not add a be verb before a base action verb. For example, avoid saying "I am live in Spain." Instead, say "I live in Spain" or "I am living in Spain."
