Indicative.—Vowel and consonant verbs in -ω inflect the present by attaching the primary endings (when there are any) to the present stem in -όε
(-ώη-). λύ_ω, τι_μῶ (τι_μά-ω), φαίνω, λείπω. The imperfect attaches the secondary endings to the present stem with the augment. See the paradigms, pp. 114, 120. For the active forms -ω, -εις, -ει, see cross463.
