Language revitalization, also referred to as language revival or reversing language shift, is an attempt to halt or reverse the decline of a language or to revive an extinct one. Those involved can include linguists, cultural or community groups, or governments. Some argue for a distinction between language revival (the resurrection of an extinct language with no existing native speakers) and language revitalization (the rescue of a "dying" language).
Languages targeted for language revitalization include those whose use and prominence is severely limited. Sometimes various tactics of language revitalization can even be used to try to revive extinct languages. Though the goals of language revitalization vary greatly from case to case, they typically involve attempting to expand the number of speakers and use of a language, or trying to maintain the current level of use to protect the language from extinction or language death. Language revitalization can face significant barriers, not the least of which can come from governments, such as a general lack of support or funding for the projects, or a system that may actively repress the minority language. Other barriers could be a lack of speakers, a lack of relevant teaching material, or vocabulary loss.
