FUTURE ACTIVE AND MIDDLE (532 ff.). FUTURE PERFECT (580 ff.)

[*] 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 628. Liquid verbs, Attic futures (538), Doric futures (540) are inflected like contract verbs in -εω; thus φανῶ φανοῦμαι, καλῶ καλοῦμαι, and πεσοῦμαι, follow ποιῶ ποιοῦμαι (385).

a. The only future perfect active from an ω-verb is τεθνήξω shall be dead (584), which is inflected like a future active. Ordinarily the periphrastic formation is used: λελευκὼς ἔσομαι shall have loosed. The future perfect passive (λελύ_σομαι shall have been loosed) is inflected like the future middle. The periphrastic forms and the future perfect passive rarely occur outside of the indicative.

[*] 660. 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 (539 d) cause to go: βιβῴην, -ῴης, -ῴη, pl. βιβῷμεν.

[*] 661. 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.

[*] 661 D. 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.
