The verb "have" is used as a helping (auxiliary) verb in constructions that form perfect tenses of main verbs. In that use, the helping verb is a conjugated form of "have": have, has, had, and the main verb appears in its past participle form.

The verb "have" can also be used as a main verb. If the tense of that main verb is a perfect tense, it will use the past participle of "have", i.e. had.

Thus a sentence can have the present perfect of "have" as its main verb:
- He has had dinner.
Here, "has" is the helping verb, and "had" is the past participle of the main verb.

A sentence can have the past perfect of "have" as its main verb:
- He had had his dinner already when I offered to buy him a sandwich, so he declined my offer.
Here, the first "had" is the helping verb (the past form of "have") and the second "had" is the past participle of the main verb.
