[1] LSJ entry for the headword at web address 1.
[2] Literally 'an acquired [formation: tu/pon] from nh/pios' (nu 325). The Suda entry reflects Etymologicum Magnum 604.26 -- commenting on nhpie/h| a)legeinh|= at Homer, Iliad 9.491 (web address 2) -- where the origin of the word nhpie/h is explained as a formation from the feminine of the possessive adjective nhpi/eios [i.e. nhpiei/h] by dropping the latter iota. See also nu 323.
See also Chantraine, who does not comment on the derivation of the word given in the Etym. Magn., but emphasizes the metrical considerations and accounts for the form by analogy with h)nore/h.
