The headword is aorist middle optative of ai(re/w, third person singular. Same glossing in other lexica; evidently quoted from somewhere. (The gloss seems to have been attracted into the middle voice, which is not normal for qe/lw/e)qe/lw; Theodoridis on Photius s.v. obelizes it and indicates a preference for qe/loi in Hesychius s.v. Latte on Hesychius regards the headword itself as quoted from Euripides, Alcestis 464.)
The same verb occurs at epsilon 844, epsilon 893, epsilon 896, epsilon 897.
