In English grammar, the pluperfect (e.g. "had written") is now usually called the past perfect, since it combines past tense with perfect aspect. (The same term is sometimes used in relation to the grammar of other languages.) English also has a past perfect progressive (or past perfect continuous) form: "had been writing".
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.

Present perfect (not progressive, perfect): "I have eaten" Present perfect progressive (progressive, perfect): "I have been eating" (While many elementary discussions of English grammar classify the present perfect as a past tense, it relates the action to the present time.
The present perfect tense is illustrated by I've left it somewhere; the past perfect (also called the preterite perfect) tense by I'd left it somewhere.
