This book is a collection of studies about forms of address in the world’s languages, with a focus on contrast and difference. The individual chapters highlight inter- and intralinguistic variation in the expression of address and its sociol-cultural functions across media, registers, geographical contexts and time – in more than 15 languages. The volume showcases the variety of approaches that exists in current address research, including the breadth of contrastive methodologies harnessing surveys and questionnaires, focus group discussions, corpus linguistics, discourse and conversation analysis to offer complementary perspectives on culture-specific address practice. This volume is for students and researchers of address and social interaction in a range of disciplines in the humanities and social sciences, including various sub-disciplines of linguistics (such as contrastive, variational and intercultural pragmatics, sociolinguistics, and morphology) and intercultural communication, as well as experts in individual languages and qualitative sociologists.
