The primary headword is a neuter noun in the nominative/accusative plural. In its plural forms this noun often means halls or palace, as typically in Homer (e.g. Iliad 9.463: web address 1).
[1] The gloss is the same form as the headword, from the noun oi)/khma, -atos, to/. See LSJ s.v; ps.-Herodian, Partitiones 81.1; and Hesychius mu 483 (s.v. me/gara).
[2] For this material see also the Synagoge, Photius (Lexicon mu175 Theodoridis), and Lexica Segueriana 296.9; cf. Hesychius mu489 (s.v. me/garon) and the scholia to Homer, Iliad 1.418 (web address 2), where the dative plural mega/roisin (in the halls) appears. The singular number of the primary headword sometimes acquires the additional connotation of sanctuary or shrine, as in the following quotation. [In her critical apparatus, Adler notes that mss GMV devoted a separate entry to the rest of the passage, beginning with me/garon, and mss GM located the new entry after mu 386.]
[3] Part of Aelian fr. 10 Hercher (Domingo-Forasté 10h, p. 21); cf. epsilon 3604 and iota 195. Adler notes that Bekker replaced me/lei (present indicative active, third person singular of me/lw), with the present active participle me/lon; also that ms M reads teleuth=s: by the law on the issue.
