The Verb To Be in the Present Simple: Affirmative, Negative and Interrogative Forms

The verb “to be” in the Present Simple is one of the most important grammar topics for English beginners. It is used to talk about people’s names, ages, jobs, nationalities, feelings, locations and descriptions.

In the present simple, the verb to be has three forms: am, is and are. Understanding how to use these forms in affirmative sentences, negative sentences and questions will help you build correct English sentences and communicate more confidently.

In this lesson, you will learn how to use am, is and are in all three forms, with simple explanations and useful examples.

1. The Verb To Be: Present Simple

The verb “to be” changes depending on the subject of the sentence.

Here is a simple table showing which form to use:

Remember:

• Use AM with I.
• Use IS with he, she and it.
• Use ARE with you, we and they.

2. The Affirmative Form

We use the affirmative form to give positive information about someone or something.

Structure

Subject + am / is / are + complement.

Examples:

• I am 15 years old.
• She is a doctor.
• He is very friendly.
• We are students.
• They are from Morocco.
• The classroom is clean.

Short Forms (Contractions)

In everyday English, we often use contractions to make sentences shorter.

Examples:

• I’m a student.
• She’s my sister.
• They’re happy.

Both full forms and short forms are correct.

3. The Negative Form

We use the negative form when we want to say that something is not true or does not describe someone or something.

To make a negative sentence, simply add not after am, is or are.

Structure

Subject + am / is / are + not + complement.

Examples:

• I am not tired.
• He is not a doctor.
• She is not at home.
• We are not late.
• They are not hungry.

Negative Contractions

We can also use contracted forms:

Examples:

• I’m not angry.
• He isn’t my brother.
• We aren’t ready.
• They aren’t at school.

Important: We say “I am not” or “I’m not”. We do not normally use “I amn’t” in standard English.

4. The Interrogative Form

We use the interrogative form to ask questions.

To make a question with the verb “to be”, we change the order of the subject and the verb.

The verb comes before the subject.

Structure

Am / Is / Are + subject + complement + ?

Examples:

• Am I late?
• Is he your brother?
• Is she a teacher?
• Are you happy?
• Are they students?
• Are we ready?

Notice how the verb moves to the beginning of the sentence.

Remember: In short answers, we usually do not use contractions in positive answers. For example, say “Yes, I am”, not “Yes, I’m”.
