Auxiliary Verbs

Auxiliary verbs are the verbs which help the main verb and give extra meaning to it. For example:

"I have studied English for three years."

The auxiliary verb have changes the tense of the sentence to present perfect, so we know the activity is ongoing.

"I studied English for three years."

In this case there is no auxiliary verb and the sentence is therefore past simple, which means the activity has finished. So auxiliary verbs are very important for understanding the meaning of a sentence!
