Abridged from Harpokration (and Photius) s.v.
[1] Demosthenes 23.53.
[2] Homer, Iliad 1.151.
[3] As (says Harpok.) in Lysias fr. 237 Sauppe (now 291 Carey OCT) -- but the observation appears confused. It probably arises from the curious use of ἀρισφαλέ'... οὐδός with a smooth breathing at Homer, Odyssey 17.196. This unparallelled use is usually taken as a form of ἡ ὁδός 'way', but the Suda may indicate that its meaning in that context is, more correctly, 'threshold'. One word in Greek for 'threshold' is in fact ὁ οὑδός (in Attic ὁδός , s.v. LSJ), but this masculine word has the rough breathing. There is a third word to take into account in discussing this confusion: τὸ οὔδας 'surface, earthen floor of a house'. This word is not, however, acceptable in the Odyssey passage, where the agreeing adjective is not neuter.
