Helping Verbs (Auxiliary Verbs)
Helping verbs – or auxiliary verbs – are the little verbs which go along with the main verb. Helping verbs don’t show the action of the subject, they just show the tense of the verb.

The main verb is like, and used to is the helping verb which tells us it was in the past.

Tonight, it will be snowing.

Helping verbs are also used in conditional sentences; these verbs help to create the state of condition.
