Relatedness in Periphrasis A Paradigm-based Perspective

Bulgarian has several relevant verbal constructions, and this chapter concentrates on those where one instance of periphrasis is embedded within another. For example, the (periphrastic) future perfect has a periphrastic form of the verb 'be' as one component, giving a construction with embedded periphrasis. The formal account proposed for these nested constructions combines a realizational approach to morphology with a lexical nontransformational framework for syntax. While periphrasis constitutes part of the morphological paradigm, and the relatedness of different periphrastic constructions can be understood in terms of the cross-categorization of features, the syntactic structure of these constructions does not mirror the same nesting. To solve this mismatch, and to capture the nesting effect, a set of rules for Bulgarian periphrastic forms is proposed, involving realization rules which are a composition of two separate rules. The complexity of nested periphrases receives a formal account, shedding light on the syntax-morphology interface more generally.
