This book is devoted to mobile stress patterns in contemporary Russian noun inflection. A classification model is proposed, and predictability of membership in all classes is given a detailed discussion on the basis of data obtained from written sources, informants and psycholinguistic experiments with nonsense words. The framework employed in the book is J. L. Bybee's conception of cognitive morphology. The model's capacity for accounting for the generalizations about stress is evaluated by comparison with more traditional approaches to morphology. Cointains bibliography.
