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). There has only been one successful instance of a complete language revival, the Hebrew language, creating a new generation of native speakers without any pre-existing native speakers as a model.
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.
Reasons for revitalization vary: they can include physical danger affecting those whose language is dying, economic danger such as the exploitation of indigenous natural resources, political danger such as genocide, or cultural danger/assimilation. In recent times alone, it is estimated that more than 2000 languages have already become extinct. The UN estimates that more than half of the languages spoken today have fewer than 10,000 speakers and that a quarter have fewer than 1,000 speakers; and that, unless there are some efforts to maintain them, over the next hundred years most of these will become extinct. These figures are often cited as reasons why language revitalization is necessary to preserve linguistic diversity. Culture and identity are also frequently cited reasons for language revitalization, when a language is perceived as a unique "cultural treasure".
