How to Use the Verb 'To Be' in English: A Simple Guide for Beginners

The verb “to be” is the most used verb in English. It appears in almost every sentence. And the good news? Once you understand it, everything else gets easier.

Let’s break it down — simply, clearly, together.

What Is the Verb “To Be”?

“To be” is a special verb in English. It doesn’t describe an action like run or eat. Instead, it connects a subject to information about that subject.

Think of it like an equals sign (=):

I am tired. → I = tired
She is a teacher. → She = teacher
They are happy. → They = happy

Easy, right? It just tells us what something is, where it is, or how it feels.

The 3 Forms: Am, Is, Are

This is the heart of the lesson. In the present tense, “to be” has three forms.

Pronoun	Verb “To Be”	Example
I	am	I am a student.
You	are	You are kind.
He	is	He is tall.
She	is	She is from Brazil.
It	is	It is cold today.
We	are	We are friends.
You (plural)	are	You are all welcome.
They	are	They are at home.

A simple trick: I → am. He/She/It → is. Everything else → are. Print it, stick it on your wall, repeat it in the shower.

How to Use “To Be” — 4 Key Situations

Short Forms (Contractions)

In everyday English, people almost never say the full form. They use contractions — shorter, faster versions.

Full Form	Contraction	Example
I am	I’m	I’m hungry.
You are	You’re	You’re amazing.
He is	He’s	He’s at school.
She is	She’s	She’s my sister.
It is	It’s	It’s a beautiful day.
We are	We’re	We’re late!
They are	They’re	They’re not home.

Negative Sentences: “Not”

To make a sentence negative, just add not after “to be”.

Full Negative	Short Negative	Example
I am not	I’m not	I’m not ready.
You are not	You aren’t / You’re not	You aren’t wrong.
He is not	He isn’t / He’s not	He isn’t here.
She is not	She isn’t / She’s not	She’s not tired.
It is not	It isn’t / It’s not	It isn’t far.
We are not	We aren’t / We’re not	We’re not lost.
They are not	They aren’t / They’re not	They aren’t coming.

Questions: Flip It!

To ask a question with “to be”, simply move the verb to the front of the sentence.

Statement: You are happy.
Question: Are you happy?

Question	Short Answer (Yes)	Short Answer (No)
Am I late?	Yes, you are.	No, you aren’t.
Are you okay?	Yes, I am.	No, I’m not.
Is he a doctor?	Yes, he is.	No, he isn’t.
Is it raining?	Yes, it is.	No, it isn’t.
Are they ready?	Yes, they are.	No, they aren’t.

Notice: in short answers, we never use a contraction for “Yes”. We say “Yes, I am.” — not “Yes, I**‘m**.” This is a small but important rule!

Past Tense: Was & Were

“To be” also has a past tense. Instead of am/is/are, we use was and were.

Present	Past	Example
I am	I was	I was very nervous yesterday.
You are	You were	You were great at the meeting!
He/She/It is	He/She/It was	She was a teacher for 20 years.
We/They are	We/They were	They were so happy together.

For negatives in the past: was not (wasn’t) / were not (weren’t)

For questions in the past: flip it again! → Was she there? Were you at the party?
