Extinct language

Language extinction is typically a result of cultural assimilation leading to language shift, and the gradual abandonment of a native language in favor of a foreign lingua franca.

As of the 2000s, a total of roughly 7,000 languages are spoken worldwide. Most of these are minor languages in danger of extinction; one estimate published in 2004 expected that some 90% of the languages spoken at that time will have become extinct by 2050.

Language death

Normally the transition from a spoken to an extinct language occurs when a language undergoes language death by being directly replaced by a different one. For example, many Native American languages were replaced by Dutch, English, French, Portuguese, or Spanish as a result of European colonization of the Americas.

After a language has ceased to be spoken as a first language, it may continue to exist as learned, second language, such as Latin.

In a view that prioritizes written representation over natural language acquisition and evolution, historical languages with living descendants that have undergone significant language change may be considered "extinct", especially in cases where they did not leave a corpus of literature or liturgy that remained in widespread use (see corpus language), as is the case with Old English or Old High German relative to their contemporary descendants, English and German. This is accomplished by periodizing English and German as Old; for Latin, an apt clarifying adjective is Classical, which also normally includes designation of high or formal register.

Minor languages are endangered mostly due to economic and cultural globalization, cultural assimilation, and development. With increasing economic integration on national and regional scales, people find it easier to communicate and conduct business in the dominant lingua francas of world commerce: English, Mandarin Chinese, Spanish, and French.

In their study of contact-induced language change, American linguists Sarah Grey Thomason and Terrence Kaufman (1991) stated that in situations of cultural pressure (where populations are forced to speak a dominant language), three linguistic outcomes may occur: first – and most commonly – a subordinate population may shift abruptly to the dominant language, leaving the native language to a sudden linguistic death. Second, the more gradual process of language death may occur over several generations. The third and most rare outcome is for the pressured group to maintain as much of its native language as possible, while borrowing elements of the dominant language's grammar (replacing all, or portions of, the grammar of the original language). A now disappeared language may leave a substantial trace as a substrate in the language that replaces it. There have, however, also been cases where the language of higher prestige did not displace the native language but left a superstrate influence. The French language for example shows evidence both of a Celtic substrate and a Frankish superstrate.

Institutions such as the education system, as well as (often global) forms of media such as the Internet, television, and print media play a significant role in the process of language loss. For example, when people migrate to a new country, their children attend school in the country, and the schools are likely to teach them in the majority language of the country rather than their parents' native language.

Language death can also be the explicit goal of government policy. For example, part of the "kill the Indian, save the man" policy of American Indian boarding schools and other measures was to prevent Native Americans from transmitting their native language to the next generation and to punish children who spoke the language of their culture of origin. The French vergonha policy likewise had the aim of eradicating minority languages.
