The paper rejects the standard view according to which every tensed verb in English agrees with its subject in person and number. It argues that person is irrelevant to all verbs except BE, and that past-tense verbs and modals (other than BE) have no number agreement features. It discusses agreement mismatches which reflect the subject's meaning, but rejects the idea that subject–verb agreement may be a semantic rule; it proposes instead a new feature ‘agreement-number’. This extra number feature applies only to the subject of a tensed verb and by default has the same value as the subject's ordinary number, while also allowing various kinds of mismatch (for I and you, and for cases of ‘semantic’ agreement). It also offers analyses of agreement with non-nominal subjects and dummy there, and shows how the analysis for Standard English generalizes easily to a range of variations found in nonstandard dialects. The theoretical basis for the analysis is Word Grammar, whose main advantage is that features are free to be assigned by rule because they are not used in classification.
