Sociolinguistics is the descriptive study of the effect of any and all aspects of society, including cultural norms, expectations, and context, on the way language is used, and society's effect on language. It differs from sociology of language, which focuses on the effect of language on society. Sociolinguistics overlaps considerably with pragmatics. Itis historically closely related to linguistic anthropology, and the distinction between the two fields has been questioned.This bookdeals with the social life of language.The field ranges from micro-analyses to broadly-based policy and planning undertakings. As such, this book draws from sociolinguistics, the sociology of language, and psycholinguistics. The relationship between language and identity - whether of an individual or a group - is a strong thread linking all the topics covered in the book. For researchers and advanced students, it gives access to the field's most pressing issues and debates, as well as providing a platform for new initiatives in sociolinguistic research.
