[1] Headword and gloss alike are single-word adjectives (hard to render into English except by these phrases), here in the masculine accusative singular or neuter nominative/accusative singular; neuter nominative if it quoted from Hesiod (cf. next note). LSJ s.v. explains that one strand of this adjective derives from kw/mh "village", another -- generating the substantive e)gkw/mion -- from a celebratory kw=mos (kappa 2265, kappa 2266).
[2] The entry so far -- also in Hesychius (epsilon282) and other lexica -- reproduces material in two sets of scholia: to Hesiod, Works and Days 344, where the headword is a variant reading for e)gxw/rion (see LSJ); and to Lucian, How to Write History 14, where the headword occurs in the "praise" sense. cf. generally kappa 2258, kappa 2259, kappa 2260, kappa 2261.
