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".
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.
