This is the first detailed explanation of the way British Sign Language works & is the product of many years experience of research & teaching sign linguistics to deaf & hearing people. It assumes no previous knowledge of linguistics or sign language & is not structured around traditional headings such as phonology morphology & syntax. Instead it is set out in such a way as to help learners & their teachers understand the linguistic principles behind the language. There are sections on BSL grammar & also on the use of BSL including social acceptability in signing variation & poetry & humour in BSL. Technical terms & linguistic jargon are kept to a minimum & the text contains many examples from English BSL & other spoken & sign languages. The book is amply illustrated & contains exercises as well as a reading list for further study. An accompanying 90-minute DVD is available from Talk With Sign Books.
