The book under review presents an analysis of past-tense forms in nonstandard varie ties of British English by including both a diachronic and a synchronic perspective. In contrast to the ordinary definition in English historical linguistics the terms strong and weak verb are used differently in this study. The term strong verb is employed in a much wider sense, which includes both verbs with vowel gradation as well as any other irregular verb. Accordingly, strong verb not only designates historically strong verbs but also historically weak verbs with a vowel mutation in the past (e.g. teach taught). The term weak verb is restricted to verbs that mark their past-tense form only with an inflectional suffix (<-ed>) without changing the quality of the stem vowel (e.g. knowed or growed).
