Without resorting to underlying representations or procedural rules, the Cognitive Linguistics framework facilitates an insightful approach to abstract phonology, offering the important advantage of restrictiveness. Cognitive Grammar provides an analysis of an entire morphophonological system in terms of a parsimonious set of theoretical constructs that all have cognitive motivation. No ad hoc machinery is invoked, and the analysis yields strong empirical predictions. Another advantage is that Cognitive Grammar can identify the meaning of morphophonological alternations. For example, it is argued that stem alternations in Russian verbs conspire to signal non-past meaning. This book is accessible to a broad readership and offers a welcome contribution to phonology and morphology, which have been understudied in cognitive linguistics.
