The headword is a two-ending adjective in the masculine (and feminine) nominative singular; see LSJ s.v. nwqh/s, -e/s, and cf. generally nu 533, nu 534, and nu 537. It occurs in, and is evidently extracted from, Homer, Iliad 11.558 (web address 1), where the poet compares the Trojan assault upon Aias to boys pummeling a stubborn donkey and only with difficulty driving it out of a cornfield.
[1] The first gloss is a masculine adjective in the nominative singular; see generally LSJ s.v., and in the Homeric scholia (see primary note). The remaining two glosses are two-ending adjectives in the masculine (and feminine) nominative singular; LSJ s.vv. The headword is similarly glossed in Photius' Lexicon (nu307 Theodoridis), the Synagoge, Hesychius nu765, Lexica Segueriana 310.18, and Etymologicum Magnum 608.2.
[2] As from ne + qe/ein "run": essentially the same etymology as in Orion [Author, Myth], Etymologicum 110.14 (s.v. nwqei/s) and Etymologicum Magnum 608.4; cf. Apollonius Sophistes, Homeric Lexicon 116.29.
