Book excerpt: This book is a tribute to Malcolm Coulthard, who has been remarkably active and influential across a wide range of English Language Studies. He is particularly well-known for his pioneering work in spoken and written discourse analysis and most recently, for his work in forensic linguistics. This collection of specially commissioned, state-of-the-art pieces by leading international linguists is dedicated to the man and his achievements and provides a showcase for the most exciting developments in applied discourse studies. All the papers share common assumptions about language study: that descriptions should be data-based, data-tested and replicable. The collection as a whole contains original and important new research on descriptions, with intriuging applications to forensic, gender and literary studies.
