Supported by contemporary evidence, this study discusses the revival of Hebrew a century ago (within two or three decades), with a focus on the actual total shift of pre-Israel Palestine's Jewish community from Yiddish and several other languages to Hebrew as an all-purpose means of communication. First, four “factors” that prevailed prior to and during the revival are discussed: the “communicative”, “political”, “religious”, and “literary.” The study then proposes schematically that the shift to Hebrew evolved in a cycle consisting of four consecutive albeit partially overlapping “steps”: (1) The children are instilled with desired language attitudes. (2) The children acquire the code, Hebrew. (3) The children transfer Hebrew, now a second language, out of the schools. (4) With these children now adults, their newly born receive Hebrew as a first language. Finally, the study suggests that, in the absence of a central authority, the revival can be seen as a case of “micro language planning,” in which potential speakers constituted “language planning agents” active in “language planning cells.” (Language revival, Hebrew, language planning, language shift, vernacular)
