The present perfect is a grammatical combination of the present tense and the perfect aspect, used to express a past event that has present consequences. An example is "I have eaten". Depending on the specific language, the events described by present perfects are not necessarily completed, as in "I have been eating" or "I have lived here for five years."
The present perfect is a compound tense in English, as in many other languages, meaning that it is formed by combining an auxiliary verb with the main verb. For example, in modern English, it is formed by combining a present-tense form of the auxiliary verb "to have" with the past participle of the main verb. In the above example, "have" is the auxiliary verb, whereas the past participle "eaten" is the main verb. The two verbs are sometimes labeled "V1" and "V2" in grammar instruction.
