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.

don't like flying in cloud.

He has already seen the aircraft.

Are they departing 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 maybecan't means impossible or unable, and should is asking for advice:

It may rain on our approach.

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

Should I pay a landing fee at this airport?

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 bedo, and have also have full verb meanings. In the following sentences, bedo, and have are full verbs and not auxiliary verbs:

did my weather forecast last night.

Is he air sick today?

Let's have a flight together!
