This paper offers an analysis of ka41, an aspectual element in Changsha Xiang Chinese. It is argued that this element occupies a position in the inner-aspectual structure of the clause, between the higher aspectual marker ta21 and the lower elements expressing a lexical result (like clean in wash clean). On the basis of its co-occurrence with various verb types, we treat ka41 as an achievement marker: when present, it blocks any reading in which the denoted event proceeds along a multi-point scale, allowing only the instantaneous, two-point scale reading in which the beginning and the endpoint of the event coincide. On the basis of its syntactic distribution we argue that the syntactic position ka41 occupies is an intermediate aspectual projection (Asp2P) in the inner aspect domain, which is sandwiched between the lowest inner aspectual projection dedicated to telicity and the highest one signaling perfectivity (or realization of the end point). We review the implications of the analysis for the aspectual domain of Mandarin clauses and point out that the intermediate inner aspectual projection (Asp2P) we introduce for Changsha appears to be a suitable syntactic position for the structural analysis of the small set of grammaticalized items generally known as “Phase complements” as well.
