\I"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.
