An extinct language (also called a dead language) is a language which no longer has any native speakers. Normally this occurs when a language undergoes language death while being directly replaced by a different one, for example, Coptic, which was replaced by Arabic, and many Native American languages, which were replaced by English, French, Spanish, or Portuguese.Language extinction also occurs when a language undergoes a rapid evolution or assimilation until it eventually gives birth to an offspring, yet, dissimilar language (or family of languages). Such is the case with Latin; an extinct (dead) language but the parent of the modern Romance languages. Likewise Sanskrit is the parent of the modern Indo-Aryan languages and Old English is the parent of Modern English. There are apparently children using Sanskrit as a revived language in Mathoor village (India) .In some cases, an extinct language remains in use for scientific, legal, or ecclesiastical functions. Sanskrit, Latin, Old Church Slavonic, Avestan, Coptic, Old Tibetan and Ge'ez are among the many extinct languages used as sacred languages.A language that does have living native speakers is called a modern language. Ethnologue claims there are 6,912 living languages known. Hebrew is an example of a formerly extinct liturgical language that has been revived to become a living language. There have been other attempts at language revival (such as Manx and Cornish), but the success of these attempts has been subject to debate, as it is not clear they will ever become the common native language of a community of speakers.
