(grammar) A perfect tense that expresses action in the past (usually completed) with consequences in the present time.

(grammar) A combination of the conditional mood and the perfect tense, roughly corresponding to English 'I would have...'

(grammar) A feature of the verb which denotes viewing the event the verb describes as a completed whole, rather than from within the event as it unfolds. For example, "she sat down" as opposed to "she was sitting down".

This is not to be confused with the perfect tense.
