An extinct language is a language that no longer has any speakers, or that is no longer in current use. Extinct languages are sometimes contrasted with dead languages, which are still known and used in special contexts in written form, but not as ordinary spoken languages for everyday communication. However, language extinction and language death are often equated.
Language loss 
Normally the transition from a spoken to an extinct language occurs when a language undergoes language death while being directly replaced by a different one. For example, Native American languages were replaced by English, French, Portuguese, Spanish, or Dutch as a result of colonization.
By contrast to an extinct language which no longer has any speakers, a dead language may remain in use for scientific, legal, or ecclesiastical functions. Old Church Slavonic, Avestan, Coptic, Biblical Hebrew, New Testament Greek, Ge'ez, Ardhamagadhi, Pali, Sanskrit and Latin are among the many dead languages used as sacred languages. Courses and active teaching still exist for these, as well as Egyptian Hieroglyphs and Maya script.
Sometimes a language that has changed so much that linguists describe it as a different language (or different stage) is called "extinct", as in the case of Old English, a forerunner of Modern English. But in such cases, the language never ceased to be used by speakers, and as linguists' subdivisions in the process of language change are fairly arbitrary, such forerunner languages are not properly speaking extinct.
Hebrew is an example of a nearly extinct spoken language (by the first definition above) that became a lingua franca and a liturgical language that has been revived to become a living spoken language. There are other attempts at language revival. In general, 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.
It is believed that 90% of the circa 7,000 languages currently spoken in the world will have become extinct by 2050, as the world's language system has reached a crisis and is dramatically restructuring.
Globalization, development, and language extinction 
As economic and cultural globalization and development continue to push forward, growing numbers of languages will become endangered and eventually, extinct. With increasing economic integration on national and regional scales, people find it easier to communicate and conduct business in the dominant languages of world commerce: English, Chinese, and Spanish.
In their study of contact-induced language change, American linguists Sarah Grey Thomason and Terrence Kaufman state that in situations of cultural pressure (where populations must 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).
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, immigrants may travel from one country to another, their children then attend school in the country, and the schools may teach them in the official language of the country rather than their native language.
