Helping verbs (auxiliary verbs) do just what their name implies. They help the main verb in the sentence by telling more about the verb's tense, mood, and voice.
Verb phrases consist of one main verb and one or more helping/auxiliary verbs.
(Every sentence needs to have at least one main verb, but not every sentence needs a helping/auxiliary verb.)Sometimes, these verbs are separated by other words.
This seems obvious, right? They are made up of verbs, so what else would they be acting as?
The point here is that they are made up of multiple words and all of the words come together to act as one part of speech, a verb.
