All vowel and consonant verbs in -ω inflect the future alike.659
Indicative.—The future active and middle add the primary endings, and are inflected like the present; as λύ_σω, λύ_σομαι. On the two endings of the second singular middle, see cross628. Liquid verbs, Attic futures ( cross538), Doric futures ( cross540) are inflected like contract verbs in -εω; thus φανῶ φανοῦμαι, καλῶ καλοῦμαι, and πεσοῦμαι, follow ποιῶ ποιοῦμαι ( cross385).
a. The only future perfect active from an ω-verb is τεθνήξω
Optative.—The inflection is like the present: λύ_σο-ι_-μι, λυ_σο-ί_-μην. In the optative singular of liquid verbs, -ιη-ν, -ιη-ς, -ιη, in the dual and plural -ι_-τον,
-ι_-την, -ι_-μεν, -ι_-τε, -ιε-ν, are added to the stem ending in the thematic vowel ο; thus φανεο-ίην φανοίην, φανέο-ι_-μεν φανοῖμεν. So in Attic futures in -άζω, as βιβάζω ( cross539 d)
Infinitive.—The future infinitive active adds -εν, as λύ_σειν from λύ_σε-εν, φανεῖν from φανέ (ς) ε-εν. The infinitive middle adds -σθαι, as λύ_σε-σθαι, φανεῖσθαι, from φανέ (ς) ε-σθαι.661D
Hom. has ἀξέμεναι, ἀξέμεν, ἄξειν. Doric has -ην, -ειν; Aeolic has -ην.662
Participle.—The future participle has the same endings as the present: λύ_σων λύ_σουσα λῦσον, φανῶν φανοῦσα φανοῦν; middle, λυ_σόμενος, φανούμενος.
