Henry George Liddell, Robert Scott, A Greek-English Lexicon

I. in pres. and impf., of females, conceive, Λάβδα κύει τέξει δὲ κτλ. Orac. ap. Hdt.5.92.β́, cf. Ar.Fr.609, Pl.Lg.789e, etc.; “κύω μῆνα ὄγδοον ἤδη” Luc.DMeretr.2.1; “κ. ἀπό τινος” Id.Gall.19: metaph., “κύει πόλις ἥδε” Thgn.39.

2. rarely c.acc., to be pregnant with, “οὐδὲ κύουσι πολλὰ κυήματα” Arist.HA543b22; “παιδίον” Luc.DMeretr.2.4: metaph., ἡ ψυχή μου ἀεὶ τοῦτο κύουσα (al. κυοῦσα）“ διῆγεν” X.Cyr.5.4.35:—Pass., to be borne in the womb, “τὰ κυόμενα παιδία” Arist.Pr.860a21, Jul.Or.2.99c.

II. in aor. Act. ἔκυ_σα, causal, of the male, impregnate, metaph., “ὄμβρος ἔκυσε γαῖαν” A.Fr.44.4:—aor. Med. ἐκυ_σάμην, of the female, conceive, “οὓς τέκε κυσαμένη” Hes.Th.125, cf. 405, h.Hom.1.4; Ζηνί by Zeus, Asius Fr.Ep.1.3 K.; “ὅσσους . . Τυφάονι κύσατο Κητώ” Euph.112.—The forms κυέω and κύω seem synonymous, but κυέω （κυῶ) is the better-attested form in Att. Prose (κύοντα only v.l. in Pl. Tht.151b, κύοντες is read in Arist.HA544a23 (v.l. κύονες, ποιοῦντες）, κύοντα ib.585a3, κυόμενα (v.l. -ούμενα) Pr.l.c., κυόμενον (v.l. -ούμενον) GA730b4, but “κυοῦντες” HA610b3; “ἐκύομεν” LXX ls.59.13).—The pres. κύω has υ^ in verse, but forms of κυ^έω can be restored by altering the accent.—The causal sense belongs only to the aor. ἔκυ_σα.
