"""Most of the 7,000 languages spoken in the world today will vanish before the end of this century, taking with them cultural traditions from all over the world, as well as linguistic structures that would have improved our understanding of the universality and variability of human language. This book is an accessible introduction to the topic of language endangerment, answering questions such as: What is it? How and why does it happen? And why should we care?
