This may be a meaningless issue, but I'm trying to think if the root "dicere", rendered as "-diction" as explanation in English, is flexible enough to admit the whole spectrum of temporal meanings by changing the preposition. At present there are two, for future and past (postdiction seems to have been coined in the 80's). The one that seems to be missing is the term for the present. Has anyone seen Diction used to accomplish this task? What do you think?
