Following Philoxenus' theory, the word is derived from a monosyllabic verb, which itself results from a syncope. The derivation is backed by a formal parallel. The difficult point, not explicit n Orion's formulation, is meaning: it is explicit in the Gudianum, which gives a more developed version of Philoxenus' explanation. Κεράω, the non syncopated form, is assumed to mean, not "to mix", but "to pour", which relied on a Homeric line (Od. 5.93) in which the verb is used for nectar: nectar was not supposed to be mixed with water, contrary to wine, therefore κέρασσε in Od. 5.93 cannot mean "mixed" but means "poured" (this is found in Porphyry and probably goes back to Aristoteles, see κεράννυμι / κέρας). And from this invented meaning, which is backed by an Aeschylean compound, the verb κρῶ "to pour" was derived and provided the etymon of κρήνη.
