This book presents a new theory of grammatical categories - the Universal Spine Hypothesis - and reinforces generative notions of Universal Grammar while accommodating insights from linguistic typology.
This study applies the relexification hypothesis to the genesis of Yiddish. The author believes Yiddish began as a Sorbian dialect relexified to High German between the 9th-12th centuries. The present study, rich in data (much of it presented as entries to a projected etymological dictionary), also suggests new diagnostic tests for identifying relexification. The presence in Yiddish of East Slavic features (e.g. pseudo-dual, gender and plural suffix assignment) suggests that the descendants of the Judaized Khazars also relexified Kiev-Polessian (northern Ukrainian and southern Belarussian) in the 15th century to Yiddish and German. Yiddish is thus a mixed West-East Slavic language and the best proof that Khazar Jews were a major component in the ethnogenesis of the Ashkenazic Jews. Two dramatic findings are that by comparing Middle High German and Slavic vocabulary and derivational machinery, it is possible (a) to "predict" with high accuracy which German components could be accepted by Yiddish and (b) whether lexicon was most likely acquired in the first or second relexification phase or thereafter. Blockage of many Germanisms also necessitated reliance on Hebrew and invented Hebroidisms. Thus the study also contributes to an understanding of the genesis of (Slavic) Modern Hebrew, relexified from Yiddish in the 19th century.
