This book aims to provide the reader with a general framework for the study of English Sociolinguistics. It will introduce the student to the fascinating world of languages in interaction and may also awaken the reader's interest in researching other aspects of this field, with a particular focus on the English language. This book can also serve as basic training in sociolinguistics, language variation, language contact, and language education for language and CLIL teachers, as they prepare for teaching tasks in the bilingual language classroom. Different ways in which language and society are interconnected and interact are presented in this book. There are many possible relations between language and society and some of them will be discussed in these pages. Social structure and organisation also determine linguistic structure and usage, thus showing that the relationship between language and society is bidirectional.
