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 past perfect progressive or past perfect continuous (also known as the pluperfect progressive or pluperfect continuous) combines perfect progressive aspect with past tense. It is formed by combining had (the past tense of auxiliary have), been (the past participle of be), and the present participle of the main verb.
The main Latin tenses can be divided into two groups: the present system (also known as infectum tenses), consisting of the present, future, and imperfect; and the perfect system (also known as perfectum tenses), consisting of the perfect, future perfect, and pluperfect. [1] [2] [3] [4]

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; "I have been to France" conveys that this is a part of my ...
