classics.osu.edu › Tense › PerfectThe future perfect tense relates action that, in the future, will be completed. Your T.A. asks you if you've done your assignment yet; you reply "Not yet, but by Friday I will have finished it". So, in English we capture both the futureness ( will) and the perfectness ( have ). To form the future perfect active indicative, find the perfect stem (3rd principle part less the final "i"), and add the personal endings.
