This volume concerns various aspects of the theory and application of language conflict phenomena seen from an interdisciplinary perspective. The focus is on linguistic, social, psychological and educational issues (conditions, constraints and consequences) involved in the status and use of languages in multilingual settings. The book is divided into four sections, which deal with: theoretical issues - such as the nature of the concepts of language maintenance; language policy and language planning; attitudes towards languages; and codeswitching and language choice.
