Sociolinguistics, as a discipline that studies the social influence on
language use, is now facing new challenges and opportunities along
with the advancement of information technology. This book invites
readers to explore various sociolinguistic concepts and theories, from
basic to cutting-edge developments, as well as their application in digital
contexts. We strive to present material in a scientific but communicative
style so that it can be accessed by students, lecturers, and general
readers.
