Perfect Tenses The three perfect tenses in English are the three verb tenses which show action already completed. (The word perfect literally means "made complete" or "completely done.") They are formed by the appropriate tense of the verb to have plus the past participle of the verb. Present Perfect: I have seen it.
In grammar, a future tense (abbreviated FUT) is a verb form that generally marks the event described by the verb as not having happened yet, but expected to happen in the future. An example of a future tense form is the French aimera, meaning "will love", derived from the verb aimer ("love").
The past tense describes a past event or a state of being.The past tense is categorized further depending on whether the action was in progress or has been completed. The four past tenses are the simple past tense, the past progressive tense, the past perfect tense, and the past perfect progressive tense.
The present tense usually describes a current event or state of being, but, oddly, the present tense can also describe past and future events. The four present tenses are the simple present tense, the present progressive tense, the present perfect tense, and the present perfect progressive tense.
