In this provocative work, Luigi Burzio argues that many common assumptions within stress theory, and phonological theory more generally, are in fact rather arbitrary. He proposes radical departures from recent tradition. In Part I he analyzes stress in the underived English lexicon, arguing that the basic accentual groups or “feet” are not monosyllabic or bisyllabic, as often assumed, but rather bisyllabic or trisyllabic. This analysis brings significant simplifications to other recent theorizing, including the elimination of standard extrametrically and all rules destressing. In Part II Professor Burzio deals with morphologically complex words, and argues that various phenomena of stress preservation, including the apparent stress “neutrality” of a class of affixes, are all predictable reflexes of a single principle of Metrical Consistency. In addition to a superior account of stress, the proposed metrical theory yields a unitary account of a wide spectrum of vowel-length alternations, in an overall conception of phonology which is modular, like that of contemporary syntax. The book makes a major theoretical contribution to the analysis of English word stress and to phonological theory.
