The present perfect is a grammatical combination of the present tense and perfect aspect that is used to express a past event that has present consequences. [1] The term is used particularly in the context of English grammar to refer to forms like "I have finished".
It is formed with the present tense of the auxiliary have (namely have or has) and the past participle of the main verb. The choice of present perfect or past tense depends on the frame of reference (period or point in time) in which the event is conceived as occurring. If the frame of reference extends to the present time, the present perfect ...
The basic (present) perfect form, with the auxiliary in the present tense, may specifically carry the meaning of perfect aspect, as in English; however in some languages it is used more generally as a past tense (or preterite), as in French and German. The use of auxiliaries and meaning of the constructions in various languages are described below.

In Ancient Greek, the perfect tense (Ancient Greek: χρόνος παρακείμενος, romanized: khrónos parakeímenos) [9] is a set of forms that express both present tense and perfect aspect (finite forms), or simply perfect aspect (non-finite forms). However, not all languages conflate tense, aspect and mood.
The terms perfective and perfect should not be confused. A perfect tense (abbreviated PERF or PRF) is a grammatical form used to describe a past event with present relevance, or a present state resulting from a past situation. For example, "I have put it on the table" implies both that I put the object on the table and that it is still there ...
