Same or similar entry in other lexica, and cf. the scholia to Homer, Iliad 1.43.
The headword is third person singular, imperfect active ('with aorist sense': LSJ), of klu/w (kappa 1844). It occurs frequently in Homer and other poetry (with or without final nu), taking a genitive of person heard (occasionally dative, sometimes with preposition) and frequently accusative of thing; also genitive of thing heard, with or without preposition (e.g. "he heard the god's words (acc.) from the messenger," but "he heard the voice (gen.) of the goddess").
[2] Though these glossing verbs are also deployed in other lexica (see above), the second of them seems the opposite of what is required.
