Language revitalization in the context of "Extinct language"

The Celtic languages (/ˈkɛltɪk/ KEL-tik) are a branch of the Indo-European language family, descended from the hypothetical Proto-Celtic language. The term "Celtic" was first used to describe this language group by Edward Lhuyd in 1707, following Paul-Yves Pezron, who made the explicit link between the Celts described by classical writers and the Welsh and Breton languages.

During the first millennium BC, Celtic languages were spoken across much of Europe and central Anatolia. Today, they are restricted to the northwestern fringe of Europe and a few diaspora communities. There are six living languages: the four continuously living languages Breton, Irish, Scottish Gaelic and Welsh, and the two revived languages Cornish and Manx. All are minority languages in their respective countries, though there are continuing efforts at revitalisation. Welsh is an official language in Wales and Irish is an official language across the island of Ireland and of the European Union. Welsh is the only Celtic language not classified as endangered by UNESCO. The Cornish and Manx languages became extinct in modern times but have been revived. Each now has several hundred second-language speakers.

Hebrew is a Northwest Semitic language within the Afroasiatic language family. A regional dialect of the Canaanite languages, it was natively spoken by the Israelites and remained in regular use as a first language until after 200 CE and as the liturgical language of Judaism (since the Second Temple period) and Samaritanism. The language was revived as a spoken language in the 19th century, and is the only successful large-scale example of linguistic revival. It is the only Canaanite language, as well as one of only two Northwest Semitic languages, with the other being Aramaic, still spoken today.

The earliest examples of written Paleo-Hebrew date to the 10th century BCE. Nearly all of the Hebrew Bible is written in Biblical Hebrew, with much of its present form in the dialect that scholars believe flourished around the 6th century BCE, during the time of the Babylonian captivity. For this reason, Hebrew has been referred to by Jews as Lashon Hakodesh (לְשׁוֹן הַקֹּדֶש, lit. 'the holy tongue' or 'the tongue [of] holiness') since ancient times. The language was not referred to by the name Hebrew in the Bible, but as Yehudit (transl. 'Judean') or Səpaṯ Kəna'an (transl. "the language of Canaan"). Mishnah Gittin 9:8 refers to the language as Ivrit, meaning Hebrew; however, Mishnah Megillah refers to the language as Ashurit, meaning Assyrian, which is derived from the name of the alphabet used, in contrast to Ivrit, meaning the Paleo-Hebrew alphabet.

Romansh (/roʊˈmænʃ, roʊˈmɑːnʃ/ roh-MA(H)NSH; sometimes also spelled Romansch and Rumantsch) is a Romance language of the Gallo-Romance and/or Rhaeto-Romance branch of languages spoken predominantly in the Swiss canton of the Grisons (Graubünden). Romansh has been recognized as a national language of Switzerland since 1938, and as an official language in correspondence with Romansh-speaking citizens since 1996, along with German, French, and Italian. It also has official status in the canton of the Grisons alongside German and Italian and is used as the medium of instruction in schools in Romansh-speaking areas. It is sometimes grouped by linguists with Ladin and Friulian as the Rhaeto-Romance languages, though this is disputed.

Romansh is one of the descendant languages of the spoken Latin language of the Roman Empire, which by the 5th century AD replaced the Celtic and Raetic languages previously spoken in the area. Romansh retains a small number of words from these languages. Romansh has also been strongly influenced by German in vocabulary and morphosyntax. The language gradually retreated to its current area over the centuries, being replaced in other areas by Alemannic and Bavarian dialects. The earliest writing identified as Romansh dates from the 10th or 11th century, although major works did not appear until the 16th century, when several regional written varieties began to develop. During the 19th century the area where the language was spoken declined due to the industrialization of Switzerland, but the Romansh speakers had a literary revival and started a language movement dedicated to halting the decline of their language.

Modern Hebrew (endonym: עִבְרִית חֲדָשָׁה, romanized: 'Ivrit ḥadasha, IPA: [ivˈʁit χadaˈʃa] or [ʕivˈrit ħadaˈʃa]), also known as Israeli Hebrew or simply Hebrew, is the standard form of the Hebrew language spoken today. It is the only extant Canaanite language, as well as one of the oldest languages to be spoken as a native language in the modern day, on account of Hebrew being attested since the 2nd millennium BC. It uses the Hebrew Alphabet, an abjad script written from right-to-left. The current standard was codified as part of the revival of Hebrew in the late 19th and early 20th centuries, and now serves as the sole official and national language of the State of Israel, where it is predominantly spoken by over 10 million people. Thus, Modern Hebrew is nearly universally regarded as the most successful instance of language revitalization in history.

A Northwest Semitic language within the Afroasiatic language family, Hebrew was spoken since antiquity as the vernacular of the Israelites until around the 3rd century BCE, when it was supplanted by a western dialect of the Aramaic language, the local or dominant languages of the regions Jews migrated to, and later Judeo-Arabic, Judaeo-Spanish, Yiddish, and other Jewish languages. Although Hebrew continued to be used for Jewish liturgy, poetry and literature, and written correspondence, it became extinct as a spoken language.

Jeju (Jeju: 제줏말; Jeju RR: Jejunmal, or Korean: 제주어; RR: Jejueo, or 제주말; Jejumal), often called Jejueo or Jejuan in English-language scholarship, is a Koreanic language originally from Jeju Island, South Korea. It is not mutually intelligible with mainland Korean dialects. While it was historically considered a divergent Jeju dialect of the Korean language, it is increasingly referred to as a separate language in its own right. It is declining in usage and was classified by UNESCO in 2010 as critically endangered, the highest level of language endangerment possible. Revitalization efforts are ongoing.

The consonants of Jeju are similar to those of the Seoul dialect of Korean, but Jeju has a larger and more conservative vowel inventory. Jeju is a head-final, agglutinative, suffixing language, like Korean. Nouns are followed by particles that may function as case markers. Verbs inflect for tense, aspect, mood, evidentiality, relative social status, formality, and other grammatical information. Korean and Jeju differ significantly in their verbal paradigms. For instance, the continuative aspect marker of Jeju and the mood or aspect distinction of many Jeju connective suffixes are absent in Korean. Most of the Jeju lexicon is Koreanic, and the language preserves many Middle Korean features and words now lost in Standard Korean. Jeju may also have a Peninsular Japonic substratum, but this argument has been disputed.

A revived language is a language that at one point had no native speakers, but through revitalization efforts has regained native speakers.

The most frequent reason for extinction is the marginalisation of local languages within a wider dominant nation state, which might at times amount to outright political oppression. This process normally works alongside economic and cultural pressures for greater centralisation and assimilation. Once a language has become marginalised in this way, it is often perceived as being "useless" by its remaining speakers, who associate it with low social status and poverty, and consequently fail to pass it on to the next generation.
