ItacismI"ta*cism\, n. [Cf. F. itacisme. See Etacism, and cf. Iotacism.] (Greek Gram.) Pronunciation of ? (eta) as the modern Greeks pronounce it, that is, like e in the English word be. This was the pronunciation advocated by Reu?hlin and his followers, in opposition to the etacism of Erasmus. See Etacism. In all such questions between ? and a? the confusing element of itacism comes in. --Alford.
