This collection of papers is aimed primarily at students and scholars with an interest in the Modern Greek language and its various applications. It is also intended as an introduction to Greek sociolinguistics. As such, it can be studied in conjunction with introductory books to sociolinguistics. The volume brings together papers that have been published in journals dedicated to Modern Greek studies and international linguistics and in conference proceedings. The selected texts are frequently quoted in publications concerned with sociolinguistics in general and Greek sociolinguistics in particular, and have thus played a part in shaping new directions in the study of Greek language. The papers are grouped in broad thematic categories: language contact, register variation (diglossia), politeness, speaker and context variation (gender in language, youth language, electronic communication), ethnographic approaches.
