Associated motion, direction and (exchoative) aspect in Ethiopian Komo

Abstract

Abstract Komo (Koman) of Ethiopia has an obligatory paradigm of deictic directional (dd) verb morphology that, among its functions, indicates direction of motion relative to a deictic reference point, associated motion and grammatical aspect when collocated with verb roots of different semantic classes. The semantic components of a motion event underlie the Komo dd system and the grammatical aspect of a predicate can be directly mapped to the bounded/unbounded path profile. The Associated Motion function contains a bounded path which entails arrival at or departure from a reference point and, as a result, imparts aspectual telicity to the predicate. The Direction function by contrast, contains an unbounded path that expresses motion towards a reference point and does not impart aspectual telicity. Further, some morphemes express exchoativity, or the ‘exiting’ of a state, a rare if unattested grammatical category.
