In this lesson, our instructor Rebekah Hendershot goes through an introduction on perfect tenses. She starts by explaining what is a perfect tense and then goes on to discuss the present perfect tense, past perfect tense, future perfect tense and irregular perfect tenses.
A verb in a perfect tense describes an action that has already been completed as of the time being discussed.
Perfect tenses are formed by adding some of the helping form to have (and, in the case of the future perfect tense, will) to the past participle form of a verb.
To form the present perfect tense, add have or has, as appropriate, to the past participle form of a verb. Use the present perfect tense to describe actions that began in the past and are still occurring in the present, and actions that began in the past and were completed at an unspecified time.
To form the past perfect tense, add had to the past participle form of a verb. Use the past perfect for actions already completed before another point in time or action.
Form the future perfect tense by adding will have to the past participle form of the verb. Use the perfect tense for actions that will be completed before or by a specific time.
