Two related perfect forms -- third person singular indicative, and masculine nominative participle -- of the verb lagxa/nw (cf. lambda 167, lambda 171, lambda 238). Each is presumably quoted from somewhere, perhaps early poetry (Bacchylides has instances of both). In Homer, the perfect varies between le/laxa with zero-grade and le/logxa with o-grade of the root.
