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

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.
