In order to be listed, a language must be classified as "endangered" in a cited academic source. * Afro-Eurasian languages * * African languages * * * List of endangered languages in Africa * * Eurasian languages * * * Asian languages * * * * List of endangered languages in Asia * * * * * List of endangered languages in Bangladesh * * * * * List of endangered languages in China * * * * * List of endangered languages in India * * * * * List of endangered languages in Indonesia * * * * * List of endangered languages in Nepal * * * European languages * * * * List of endangered languages in Europe * * * Russian languages * * * * List of endangered languages in Russia * Australian languages * * List of Australian Aboriginal languages * * List of endangered languages in Papua New Guinea * North and South American languages * * List of endangered languages in North America * * * List of endangered languages in Canada * * * List of endangered languages in Central America * * * List of endangered languages in Mexico * * * List of endangered languages in the United States * * List of endangered languages in South America * * * List of endangered languages in Brazil * * * List of endangered languages in Colombia * Pacific languages * * List of endangered languages of the Pacific SIL Ethnologue (2005) lists 473 out of 6,909 living languages inventorized (6.8%) as "nearly extinct", indicating cases where "only a few elderly speakers are still living"; this figure dropped to 6.1% as of 2013.〔Lewis, M. Paul, Gary F. Simons, and Charles D. Fennig (eds.). 2013. Ethnologue: Languages of the World, Seventeenth edition. Dallas, Texas: SIL International. Online version: (Summary by language status )〕 In order to judge if a language is endangered, the number of speakers is less important than their age distribution. There are languages in Indonesia reported with as many as two million native speakers alive now, but all of advancing age, with little or no transmission to the young. On the other hand, while there are only 30,000 Ladin speakers left, almost all children still learn it as their mother tongue, thus Ladin is not currently endangered. Similarly, the Hawaiian language has only about 1,000 speakers but it has stabilized at this number, and there is now school instruction in the language, from preschool through the 12th grade. Thus the language is classified as merely vulnerable. While there are somewhere around six or seven thousand languages on Earth today, about half of them have fewer than about 3,000 speakers. Experts predict that even in a conservative scenario, about half of today's languages will become extinct within the next fifty to one hundred years. == See also == * Endangered language * Language families and languages * Language policy * Lists of extinct languages * List of last known speakers of languages * List of revived languages 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lists of endangered languages」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
