Language Revitalization is an emerging field, its theoretical foundations as well as its models of practice are still developing. Many publications are devoted to the fundamental task of increasing the knowledge base by reporting on revitalization projects on specific languages, often in specific communities. It is an attempt to halt or reverse the decline of a language or to revive an extinct one. Language Revitalization is often deemed necessary because of the sheer amount of linguistic diversity being lost. In recent times, it is estimated that more than 2000 languages have already become extinct around the world.
