Usage-based linguists and psychologists have produced a large body of empirical results suggesting that linguistic structure is derived from language use. However, while researchers agree that these results characterize grammar as an emergent phenomenon, there is no consensus among usage-based scholars as to how the various results can be explained and integrated into an explicit theory or model. Building on network theory, the current paper outlines a structured network approach to the study of grammar in which the core concepts of (...) syntax are analyzed by a set of relations that specify associations between different aspects of a speaker’s linguistic knowledge. These associations are shaped by domain-general processes that can give rise to new structures and meanings in language acquisition and language change. Combining research from linguistics and psychology, the paper proposes specific network analyses for the following phenomena: argument structure, word classes, constituent structure, constructions and construction families, and grammatical categories such as voice, case and number. The article builds on data and analyses presented inDiessel but approaches the topic from a different perspective. (shrink)

Voice: Malagasy presents morphologically distinct verbs built from the same root which assign different grammatical cases to DPs with given theta roles, yielding Ss that are theta equivalent, and, with appropriate choice of DPs, logically equivalent, much like active and agented passive Ss in English. The problem is to derive and interpret such Ss so as to yield these judgments of semantic equivalence as theorems. Our solution, which is purely structural, invoking no notion of ‘subject’, ‘topic’, ‘pivot’, ‘trigger’, etc., is (...) simply an explicit syntactic and semantic interpretation of voice affixes. Deriving Ss built from verbs in different voices involves no A movement of DPs. Voice morphology determines the distinctive syntactic and semantic properties of nuclear clauses. This supports that “Variation of language is essentially morphological ...” (Chomsky 1995:7). (shrink)
