Aorist imperative of r(u/omai, extracted from Homer, Iliad 17.645, where Ajax prays to Zeus for respite from the fog (web address 1).
The gloss appears, by its accentuation, to be an aorist active infinitive of lutro/w; but it should be the aorist middle imperative, lu/trwsai, with accent on the first syllable.
cf. rho 311.
