This post will cover the pluperfect indicative active. There is no pluperfect infinιtive, subjunctive or optative. The pluperfect tense has completed aspect and past time, equivalent to the English, ”I had done.”
The pluperfect indicative active is based on the perfect active tense stem. To form the pluperfect, take the perfect active tense stem and prefix it with the past indicative augment. To this stem add the appropriate ending for the person and number (assuming tense, mood and voice for this post are fixed, of course).
