Etymology

Origin of abugida

First recorded in 1960–65; from Geez ʾabugidā, extracted from ʾa(lf), b(et), g(äml), d(änt), the first four consonants of the Geez script arranged in the order of Semitic writing systems with the first four vowel sounds of Geez in their traditional order ( ä, u, i, a ); later used in an extended sense by U.S. linguist Peter T. Daniels (born 1951) in Fundamentals of Grammatology (1990); abjad ( def. )
