S. aen adv. “should be; ?may it be that” (Category: Guess, Suppose)
Carl Hostetter suggested (VT31/16) that this may be a cognate of Q. nai “be it that”, since in combination with the future verb estathar it resembles the nai + future construct of the Quenya subjunctive. David Salo suggested instead (GS/228) that it might be a pronominal subject of the same verb, though with less conviction. This entry follows Carl Hostetter’s theory. @@@ In VT50/13 Carl Hostetter suggested an alternate theory, that this is a subjunctive passive voice marker, vs. indicative passive voice marker en.
