Verb To Be: Am, Is, Are, Was, Were Explained
The 8 forms of English's most important verb, explained with examples and contractions.
Written by Bryan López, Profesor de inglés · Updated
The verb to be has 8 forms: be, am, is, are, was, were, being, and been. In the present, it's am, is, and are (I am, he is, we are); in the past, it's was and were (I was, they were). It's the most used verb in English and the foundation of almost every sentence you'll build.
Verb to be in the present
Verb to be in the past
Negatives: isn't, aren't, wasn't, weren't
To make the verb to be negative, add "not" right after it: I am not (I'm not), you are not (you aren't / you're not), he is not (he isn't / he's not). The past works the same way: I was not (I wasn't), you were not (you weren't). You never need "don't" or "doesn't" with the verb to be, that mix-up usually comes from learning the Present Simple first.

Questions: Am I...? Is he...? Was she...?
To ask a question, the verb to be moves to the front of the sentence, before the subject: Are you ready? Is she your sister? Was he at home? Were they happy? You don't use "do" or "does" to ask with the verb to be, unlike the Present Simple with other verbs (Do you like...? vs. Are you...?).
Present or past: which one do I use
Use am/is/are to talk about now, general facts, or what you're like: I am a teacher. She is tired right now. Use was/were to talk about something that already happened, usually with a past time word: I was at the gym yesterday. They were happy last year. Switching from is/are to was/were is the clearest signal you're talking about the past.
Common mistakes learners make with the verb to be
Using "have" instead of "be" for age. Many languages say the equivalent of "I have 20 years," but English uses the verb to be: "I am 20 years old," never "I have 20 years." Dropping the verb to be before an adjective. In English it's never optional, even in short sentences: don't say "She happy," say "She is happy." Using "make" for the weather. "It's hot" uses the verb to be, not "make": weather in English almost always goes through the verb to be, not "make."

Was goes with I, he, she, it (singular). Were goes with you, we, they. Both are the past of the verb to be: am/is becomes was, are becomes were.
How do you make the verb to be negative?
Add "not" right after the verb: is not (isn't), are not (aren't), was not (wasn't), were not (weren't). You never use "don't" or "doesn't" with the verb to be.
How do you ask questions with the verb to be?
The verb moves to the front of the sentence, before the subject: Are you...? Is she...? Was he...? Were they...? You don't need "do" or "does".
Why does English say "I am 20 years old" instead of "I have 20 years"?
Because English expresses age with the verb to be, not "have". Saying "I have 20 years" is a direct translation from other languages that sounds wrong in English; the correct form is always "I am + number + years old."
