Is have a helping verb

Helping verbs “help” the main verb in a sentence by adding detail to the main verb. There are two types of helping verbs. One type creates verb tenses by clarifying when an action happens, and the other type of helping verb establishes the mood of a sentence.

So when should you use each type — and when should you use a linking verb instead?

Auxiliary verbs help express verb tense in a sentence.

The three most common auxiliary verbs are to be, to have, and to do — and all of their verb forms.

• to be - am, is, are, was, were, be, been, being
• to have - have, has, had, having
• to do - do, does, did

Auxiliary verbs always appear with an action verb in a sentence to create a verb phrase.

When auxiliary verbs appear in a sentence, they’re paired with the past or present participle form of an action verb to create different verb tenses, particularly the perfect tenses and the progressive tenses.

You can use forms of be to show progressive tenses:

• I amhaving another
  is must a helping verb
  is could a helping verb
