- Endangered language
An endangered language is a language that is at risk of falling out of use. If it loses all its native speakers, it becomes a dead language. If eventually no one speaks the language at all it becomes an "extinct language". The total number of languages in the world is not known. Estimates vary depending on many factors. Michael E. Krauss estimated that there were about 6,000 languages in active use, as of 2007. UNESCO also uses this figure. Krauss goes on to define languages as "safe" if children will probably be speaking them in 100 years; "endangered" if children will probably not be speaking them in 100 years (approximately 60-80% of languages fall into this category); and "moribund" if children are not speaking them now.
Number of languages
The total number of contemporary languages in the world is not known. Estimates vary depending on the extent and means of the research intended to discover them, the definition of a distinct language and the current state of knowledge concerning the identities and vital statistics of the various peoples of the earth. Even the number of languages that are known varies as some of them become extinct or are newly discovered within the lifetimes of the active investigators.
One of the most active research agencies is SIL International, which maintains a database, Ethnologue, kept up-to-date by the contributions of linguists globally. Its 2005 count of the number of languages in its database, excluding duplicates in different countries, is 6,912, of which 32.8% (2,269) are in Asia and 30.3% (2,092) are in Africa. This contemporary tally must be regarded as a variable number within a range. Michael E. Krauss reported in 2007: "The worldwide total figure I have been using is 6,000 extant languages, a nice round figure that happens to be one millionth of the human population, a kind of middle figure ...."
Krauss defines languages as safe if children will probably be speaking them in 100 years, endangered if children will probably not be speaking them in 100 years, and "moribund" if children are not speaking them now; He estimates 15-30% (or 900-1,800) of languages are moribund.
While there is no definite threshold for identifying a language as endangered, three main criteria are used as guidelines:
- The number of speakers currently living.
- The mean age of native and/or fluent speakers.
- The percentage of the youngest generation acquiring fluency with the language in question.
Some languages, such as those in Indonesia, may have tens of thousands of speakers but may be endangered because children are no longer learning them, and speakers are in the process of shifting to using the national language Indonesian in place of local languages.
In contrast, a language with only 100 speakers might be considered very much alive if it is the primary language of a community, and is the first (or only) language of all children in that community, actually spoken.
Asserting that "Language diversity is essential to the human heritage," UNESCO's Ad Hoc Expert Group on Endangered Languages offers this definition of an endangered language: "... when its speakers cease to use it, use it in an increasingly reduced number of communicative domains, and cease to pass it on from one generation to the next. That is, there are no new speakers, adults or children."
UNESCO's online Atlas of the World's Languages in Danger categorises 2,500 languages in five levels of endangerment: unsafe, definitely endangered, severely endangered, critically endangered and extinct. More than 200 languages have become extinct around the world over the last three generations.
Once a language is determined to be endangered, there are two basic steps that need to be taken in order to stabilize or rescue the language. The first is language documentation and the second is language revitalization.
Language documentation is the process by which the language is documented in terms of its grammar, its lexicon, and its oral traditions (e.g. stories, songs, religious texts).
Language revitalization is the process by which a language community through political, community, and educational means attempts to increase the number of active speakers of the endangered language. This process is also sometimes referred to as language revival or reversing language shift.
Another option is "post-vernacular maintenance": the teaching of some words and concepts related to the lost language - rather than revival proper.
