Abstract
Russian perfectivity paradigms raise a complex network of formal issues for the projection architecture of LFG, including the structure of morphological representation and its relationship to the c-, f- and a-structures, with some consequences that appear to favor description-by-analysis over co-description for semantic interpretation. This paper presents the data and navigates its formal implications, suggesting in the end that Paradigm Function Morphology allows a clear description of the Russian facts that is equally compatible with both co-description and description-by-analysis, while permitting the elimination of m-structure.
