The headword, a Doric and Aeolic form, is the nominative (and vocative) singular form of the feminine Attic substantive σάλη ; see generally LSJ s.v. Photius s.v. (see next note) adds 'thus Aeschylus'. This dialect form of the noun is nowhere extant in Aeschylus, but in his fr. 319 Nauck the gloss σάλη γὰρ ἡ φροντίς attaches to the phrase ἀσαλὴς μανία ("thoughtless madness").
[1] The gloss is a feminine noun in the nominative singular; see generally LSJ s.v. and cf. phi 733. The headword is similarly glossed in Hesychius, Photius' Lexicon, and s.v. σάλος in the Synagoge. See also sigma 59 (end).
