Three Kinds of Verbs

1. Auxiliary Verbs: Be, Do, Have

These are used to change tenses or to make questions and negative sentences. Many teachers and students call auxiliary verbs “helping verbs” because they help the main verb of a sentence.

I don't like traveling to cold countries.

He has already seen the movie.

Are they leaving now?

2. Modal Auxiliary Verbs: Can, Will, May, Should, etc.

These are similar to the auxiliary verbs be, do, and have because they help a main verb in a sentence. They are different because they each have a special meaning.

In the following examples, may means maybe, can't means impossible or unable, and should is asking for advice:

It may rain tonight.

We can't get to the airport in five minutes.

Should I pay a tip for that in Italy?

3. Full Verbs: Go, Play, Sing, etc.

These are all the other verbs in the English language. We can also call these verbs the main verbs of a sentence. It is very important to realize that be, do, and have also have full verb meanings. In the following sentences, be, do, and have are full verbs and not auxiliary verbs:

I did my homework last night.

Is he sick today?

Let's have lunch together!

We didn't sing any of my favourite songs.

They go to yoga after work.

Do we play basketball tonight?
