David Brazil's pioneering work on the grammar of spoken discourse ended at A Grammar Of Speech (1995) due to his untimely death. Gerard O'Grady picks up the baton in this book and teststhedescription of usedlanguageagainst a spoken corpus. He incorporates findings from the last decade of corpus linguistics study, notably concerning phrases and lexical items larger than single orthographic words and ellipsis. He demonstrates theadded communicative significance that the incorporation of two systems of intonation ('Key' and 'Termination') bring to the grammar. O'Grady reviews the literature andcovers the theorybefore moving on to a practical, analytic section. His final chapter reviews the arguments, maps the road ahead and lays out the practical applications of the grammar. The book will be of great interest to researchers in applied linguistics, discourse analysis and also EFL/ESL.
