ῥᾶ

ῥᾶ, Adv.

A easily, Alcm.42, S.Fr.1086, Ion Trag.66. [Codd. vary between ῥᾶ and ῥᾴ; only ῥᾴ ([etym.] ῥάι) seems to be admitted by A.D.Adv. 156.8, Eust.163.20, but ῥᾶ is prob. correct Attic and [dialect] Dor. for Ρᾱᾰ whence [dialect] Ep. Ρῆα (written ῥεῖα in Hom. but ῥήα in Alc.Supp.12.7), later [dialect] Ion. ῥέα (q.v.); cf. [dialect] Aeol. βρᾷ.]
