The primary auxiliary verbs in English are be, do and haveThey are irregular verbs and can be used as main verbs.

Do they all speak Spanish?

 The helping verb do changes this sentence into a question.

 

An important difference between auxiliary verbs and main verbs us that auxiliary verbs and main verbs is that auxiliaries are never alone in a sentence.

 

We cannot remove the main verb from a sentence, leaving only auxiliary verb because auxiliaries don't have any meaning without a main verb.

This usually happens when answering questions:

 

Do you swim? Yes I do.
