Understanding the discourse of text messaging has profound implications for society. SMS messaging has impacted considerably on how we communicate with others. At the same time, negative, sometimes alarmist media coverage continues to fuel debate surrounding its 'damaging' effects on language and children's literacy. To what extent is this true? Should we worry about this communication tool or embrace it?Drawing on a range of academic sources from various fields, this book describes the language used in a corpus of over 11,000 text messages, as yet the largest collection in the UK. In particular, the book defines text messaging as a language variety shaped by users' creative responses to the functions and limitations of the medium. This is an essential book for upper level undergraduates and postgraduates studying discourse analysis, as well as educators wanting to understand this important new form of discourse.
