Two more contexts for Ge‘ez *u > u and three for *a > ǝ

Abstract

The main Ge‘ez (Classical Ethiopic) verbal adjective is characterized by an ǝ-u vowel melody. Based on cognate evidence, the most basic form of this adjective, 0₁-stem 1ǝ2u3, derives from a *1a2uː3- pattern and thus shows assimilation of *aCuː > ǝCu. This assimilation does not operate in a set of specialized numerals shaped like 1ä2u3, which should be reconstructed as *1a2u3- with short *u. Short *u also yields Ge‘ez u in the nonaccusative case of the masculine cardinal numerals, like *ɬalaːθtu > śälästu ‘three’; this ending goes back to the Proto-Semitic diptotic nominative. The assimilation of *aCuː > ǝCu, on the other hand, also affected the personal pronoun *huːʔa-tuː > wǝʾǝtu, the perfect of fientive verbs like *gabaruː > gäbru ‘they did’, and the jussive of stative verbs like *yitrapuː > yǝtrǝfu ‘may they remain’. Ə was leveled to other parts of these paradigms, solving several longstanding problems of Ge‘ez morphology.
