This volume is concerned with the role of the lexicon, in particular its inflectional morphology, in mediating between the substantively different categories of syntax and phonology. In the first part of the book Professor Anderson looks at the central role of the paradigm in reconciling the demands of syntactic categorization with the available means of expression. He examines the expressive role of inflection, illustrating his argument with Old English verb morphology. In the second part of the book the author pursues the notion of grammatical periphrasis. He starts out from its role as a solver of the problem of defective or incomplete paradigms and then compares it with other analytic expressions. He concludes with a discussion of why studies of grammatical periphrasis have focused on verbal constructions.
