Local grammars and diachronic speech act analysis

Abstract This paper proposes a method that is designed to facilitate diachronic speech act analysis. The proposed method draws on the corpus linguistic concept of local grammar – an approach which seeks to account for, not the whole of a language, but one meaning or function only. Local grammar descriptions capture both formal and semantic regularities of speech act realisations, and local grammars offer a more reliable way to quantify speech act realisations across time. It is particularly in this respect that it is argued that a local grammar approach can be useful for diachronic speech act studies, which is demonstrated subsequently by tracing one particular speech act, namely “apology”, in a sample of the Corpus of Historical American English (coha).
