The Verb "To Be" Explained

This graphic shows how the different forms are used. (Notice that there are short forms too.) "To be" is a special verb because it can be used as a main verb or an auxiliary verb. As a main verb, it means "exist," "occur," or "happen." As an auxiliary verb (or helping verb), the meaning comes from the verb it is helping. Look at these examples:

"To be" as a main verb:

• I am here.
(I "exist" here.)
• The meeting was in London.
(The meeting "happened" in London.)

"To be" as an auxiliary verb:

• I am working at home.
(Here, "to be" is an auxiliary verb helping the verb "to work.")
• Tom was painting the fence yesterday.
(Here, "to be" is an auxiliary verb helping the verb "to paint.")

When used as an auxiliary verb, "to be" helps to show the tense of the verb it is helping.

"Am," "is," and "are" are used to show the present progressive tense.

For example:

• Tom is cleaning the car.

"Was" and "were" are used to show the past progressive tense.

For example:

• Tom and Alice were cleaning the car.

(1) As main verbs, they are often used to link something to a description.

• I am happy.
• He is a policeman.
• We are on the bus.
(Used like this, the verb "to be" is called a linking verb.)

"Is" and "are" are used in a similar way in two very common constructions that start with "it" or "there."

• It is cold.
• There is one reason.
• There are two reasons.

(2) As auxiliary verbs, "am," "is," and "are" are used to form the present progressive tense.

"Was" and "Were" have two common uses:

(1) As main verbs, they are often used to link something to a description.

• I was happy.
• He was a policeman.
• We were on the bus.
(Just as before, the verb "to be" is a linking verb. This time though, they are in the past tense.)

"Was" and "were" are also used in those two constructions starting "it" or "there."

• It was cold.
• There was one reason.
• There were two reasons.

(2) As auxiliary verbs, "was" and "were" are used to form the past progressive tense.

• You were being silly.
(As before, the verb "to be" appears twice. Once as an auxiliary verb ("were") and once as a main verb ("being"). The verb phrase "were being" is an example of the past progressive tense.)

(2) As a present participle, "being" is used as an auxiliary verb in a passive sentence.

• Tom is being promoted this afternoon.
(In a passive sentence, the action of the verb is done to the subject. So, the action of the verb "to promote" is happening to the subject "Tom.")
