The study of code switching is potentially the most creative aspect of bilingual speech. The topic has certainly aroused the curiosity of many researchers, and a host of different features of it have been studied. Sociolinguists have looked into speech communities, both monolingual and bilingual, trying to establish reasons for, changes of style and language switching. Sociolinguistics Study of Code Switching is concerned with aspects of code switching as a societal phenomenon among bilinguals. Chapters in the book integrate theoretical perspectives and analysis of the patterns of code switching in bilinguals’ discourse. The sociolinguistic variables are discussed in terms of three parameters; physical setting, topic and participant roles. This book will be valuable to students of sociolinguistics as well as educators and all those who come into contact with the study of bilingualism and code switching. In addition, the book can also be used as a guide or source of information especially to future researchers interested in the field of code switching.
