The document defines and provides examples of auxiliary verbs and modal auxiliary verbs in English. Auxiliary verbs like be, have, and do are used to form tenses, passive voice, questions, and tags. They do not have lexical meaning on their own. Modal auxiliary verbs like can, may, must are used to express meanings like certainty, possibility, suggestions, obligations, and ability. Both auxiliary verb types help convey grammatical and functional meaning along with the main verb.

2. AUXILIARY VERB

3. What is an auxiliary verb?
Besides acting as the main verb of a sentence, verbs are
also
helpful in a number of other ways, which are not so
obvious.
There are also auxiliary or 'helping' verbs that are used in a
variety of ways. The main auxiliary verbs are be, have and
do.
Auxiliary verbs or auxiliaries do not have a lexical meaning,
but add to the grammatical or functional meaning of the
main
verb. It is important to note that some auxiliary verbs can
also
be used as full lexical verbs (meaning they convey a lexical
meaning), depending on the context.

4. They are used with main verbs to make specific tenses:
He is coming. (present continuous)
She wasn't driving. (past continuous)
We haven't seen an eclipse before. (present perfect)
She had dropped her keys. (past perfect)
The verb be + a past participle is also used to make passive forms:
The road is mended once a year.
The engines are made in Germany.
The votes are being counted in the hall.
The whales had been driven onto the shore.
The auxiliary verbs are used to make questions:
Do you want a drink?
Don't you like opera?
Have you finished the work yet?
Which train do you think you'll catch?

5. Auxiliary verbs are used to make exclamations:
Wasn't she awful!
Haven't you grown!
Didn't they do well!
Isn't it freezing!
To make questions tags:
We're very happy, aren't we?
It's cold, isn't it?
You don't like fish, do you?
You haven't had a happy childhood, have you?
Note that the verb to be is the most common verb in English and it is the only one
that can operate as both a main verb and an auxiliary verb. It doesn't need any
additional help to make questions or negatives.
I am very happy.
Am I very happy?
I'm not very happy.
Compare this with the verbs do and have which need additional help to make
questions
and negatives.
I have a very large nose. I don't have a very large nose.
I do my piano practice at 6 o'clock. I don't do my piano practice.
