This tense, in respect to time, is the same as the last, but implies the imperfection of the action, and denotes its progression.

Preter Pluperfect.
Sing.I hadThou hadstHe had}written.
Plur.We hadYe or you hadThey had}

This tense denotes that an action was perfected before another action was done.

Plusquam Preterite Imperfect.
Sing.I had beenThou hadst beenHe had been}writing.
Plur.We had beenYe had beenThey had been}

This tense, in respect to time, is more than past, and in respect to action is imperfect. It denotes that an action was going on, or in a state of progression, before another action took place, or before it was perfected; as, “I had been writing before you arrived.”

Future Indefinite.
Sing.I shallThou shaltHe shall}write.
Plur.We shallYe or you shallThey shall}
OR
Sing.I willThou wiltHe will}write.

These compound tenses denote the futurity of an action indefinitely, without any reference to its completion. The meaning of the several persons has been already explained.

Future Imp. Progressive.
I shall or will beWe shall or will be}
Thou shalt or wilt beYe shall or will be}writing.

This tense agrees with the former in respect to time, but differs from it in this, that the former has no reference to the completion of the action, while the latter expresses its imperfection and progression.
