This book looks at the nature of free word order and phrase structure, with particular reference to a single endangered language - Kiowa.Drawing on data from Kiowa, a member of the largely undescribed Kiowa-Tanoan language family, this book reveals that classically nonconfigurational languages can nonetheless exhibit configurational effects. This approach challenges widespread assumptions of linguistic theory and throws light on the syntactic structures and ordering principles of Universal Grammar.Drawing on data from Kiowa, a member of the largely undescribed Kiowa-Tanoan language family, this book reveals that classically nonconfigurational languages can nonetheless exhibit configurational effects. This approach challenges widespread assumptions of linguistic theory and throws light on the syntactic structures and ordering principles of Universal Grammar.What is the nature of syntactic structure? Why do some languages have radically free word order ('nonconfigurationality')? Do parameters vary independently (the micro-view) or can they co-vary en masse (the macro-view)? Mirrors and Microparameters examines these questions by looking beyond the definitional criterion of nonconfigurationality - that arguments may be freely ordered, omitted, and split. Drawing on data from Kiowa, a member of the largely undescribed Kiowa-Tanoan language family, the book reveals that classically nonconfigurational languages can nonetheless exhibit robustly configurational effects. Reconciling the cooccurrence of such freedom with such rigidity has major implications for the Principles and Parameters program. This approach to nonconfigurational languages challenges widespread assumptions of linguistic theory and throws light on the syntactic structures, ordering principles, and nature of parametrization that comprise Universal Grammar.1.
