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 ...
Unlike the present perfect, the past perfect can readily be used with an adverb specifying a past time frame for the occurrence. For example, it is incorrect to say * I have done it last Friday (the use of last Friday , specifying the past time, would entail the use of the simple past , I did it , rather than the present perfect).
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.

In traditional Latin and Ancient Greek grammar, the perfect tense is a particular, conjugated -verb form. Modern analyses view the perfect constructions of these languages as combining elements of ...

A verb whose conjugation follows a different pattern is called an irregular verb. This is one instance of the distinction between regular and irregular inflection, which can ...
v. t. e. In linguistics, aspect is a grammatical category that expresses how a verbal action, event, or state, extends over time. For instance, perfective aspect is used in referring to an event conceived as bounded and unitary, without reference to any flow of time during the event ("I helped him"). Imperfective aspect is used for situations ...
