Question

Which verb form is used to indicate the perfect progressive tense

Answer 1

Hmm, any selections?

Answer 2

Perfect ; The perfect form is the verb tense used to indicate a completed, or "perfected," action or condition. Verbs can appear in any one of three perfect tenses: present perfect, past perfect, and future perfect.

Verbs in the perfect form use a form of "have" or "had" + the past participle. (It is the form of the helping verb that indicates the tense.)

Progressive ; The progressive form is a verb tense used to show an ongoing action in progress at some point in time. It shows an action still in progress. Verbs can appear in any one of three progressive tenses: present progressive, past progressive, and future progressive.

The verbs in the progressive form use a form of "to be" + the present participle (an -ing verb). (It is the form of the helping verb that indicates the tense.)
