What are helping verbs
& verb phrases?

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. 

What is a verb phrase?

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.
Verb phrases
  • When we ask questions, the auxiliary verb often comes at the beginning of the sentence and the main verb comes later.
  • Words like never, not, and the contraction n't are not part of the verb. They are adverbs.

Verb Phrases Act as Verbs

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.

The cheesecake might be exploding.

Might be exploding is telling us what the cheesecake is doing (an action).

Did you call Owen?

Did call is asking what you did (an action).

Owen has become a great cook.

Has become is telling us Owen's state of being (a state of being verb).

Sentence Diagramming & Helping Verbs

Sentence diagrams show us how parts of sentences are related. They make the relationships between words, phrases, and clauses visual. They are awesome. :) Verb phrases are diagrammed on horizontal lines right after the subject.
