Endangered language in the context of "Acquaviva Collecroce"

The Northwest Caucasian languages, also called West Caucasian, Abkhazo–Adyghean, Abkhazo–Circassian, Circassic, or sometimes Pontic languages (from Ancient Greek, pontos, referring to the Black Sea, in contrast to the Northeast Caucasian languages as the Caspian languages), is a family of languages spoken in the northwestern Caucasus region, chiefly in three Russian republics (Adygea, Kabardino-Balkaria, Karachay-Cherkessia), the disputed territory of Abkhazia, Georgia, and Turkey, with smaller communities scattered throughout the Middle East.

The group's relationship to any other language family is uncertain and unproven. One language, Ubykh, became extinct in 1992, while all of the other languages are in some form of endangerment, with UNESCO classifying all as either "vulnerable", "endangered", or "severely endangered". Within the Northwest Caucasian languages, only Abkhaz has a first-set code in the ISO 639 standard.

An Indigenous language, or autochthonous language, is a language that is native to a region and spoken by its Indigenous peoples. Indigenous languages are not necessarily national languages but they can be; for example, Aymara is both an Indigenous language and an official language of Bolivia. Also, national languages are not necessarily Indigenous to the country.

Many Indigenous peoples worldwide have stopped the generational passage of their ancestral languages and have instead adopted the majority language as part of their acculturation into their host culture. Furthermore, many Indigenous languages have been subject to linguicide (language killing). Recognizing their vulnerability, the United Nations proclaimed 2019 the International Year of Indigenous Languages "to draw attention to the critical loss of Indigenous languages and the urgent need to preserve, revitalize and promote Indigenous languages."

Sardinia (/sɑːrˈdɪniə/ sar-DIN-ee-ə; Sardinian: Sardigna [saɾˈdiɲːa]; Italian: Sardegna [sarˈdeɲɲa] ), officially the Autonomous Region of Sardinia, is the second largest island in the Mediterranean Sea after Sicily, and one of the twenty regions of Italy. It is located 200 km west of the Italian Peninsula, 200 km north of Tunisia, and 16.45 km south of the French island of Corsica. Sardinia is one five Italian regions with statutory domestic autonomy. It is divided into six provinces and two metropolitan cities. Cagliari is the capital and largest city, followed by Sassari. It has over 1.5 million inhabitants as of 2025.

Sardinia's indigenous language and the Algherese dialect of Catalan are recognized by both regional and national law as two of Italy's twelve official linguistic minorities, albeit gravely endangered; regional law provides some degree of protection and recognition of the island's other minority languages: the Corsican-influenced Sassarese and Gallurese, and Tabarchino Ligurian.

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.

Aramaic (Jewish Babylonian Aramaic: ארמית, romanized: ˀərāmiṯ; Classical Syriac: ܐܪܡܐܝܬ, romanized: arāmāˀiṯ) is a Northwest Semitic language that originated in the ancient region of Syria and quickly spread to Mesopotamia, the southern Levant, Sinai, southeastern Anatolia, the Caucasus, and Eastern Arabia, where it has been continually written and spoken in different varieties for over 3,000 years.

Aramaic served as a language of public life and administration of ancient kingdoms and empires—particularly the Neo-Assyrian Empire, Neo-Babylonian Empire, and Achaemenid Empire—and as a language of divine worship and religious study within Judaism, Christianity, and Gnosticism. Several modern varieties of Aramaic are still spoken. The modern eastern branch is spoken by Assyrians, Mandeans, and Mizrahi Jews. Western Aramaic is still spoken by the Muslim and Christian Arameans (Syriacs) in the towns of Maaloula, Bakh'a and Jubb'adin in Syria. Classical varieties are used as liturgical and literary languages in several West Asian churches, as well as in Judaism, Samaritanism, and Mandaeism. The Aramaic language is considered endangered, with several varieties used mainly by the older generations. Researchers are working to record and analyze all of the remaining varieties of Neo-Aramaic languages in case they become extinct.

The Mingrelian or Megrelian language (მარგალური ნინა margaluri nina) is a Kartvelian language spoken in Western Georgia (regions of Mingrelia and Abkhazia), primarily by the Mingrelians. Mingrelian has historically been only a regional language within the boundaries of historical Georgian states and then modern Georgia, and the number of younger people speaking it has decreased substantially, with UNESCO designating it as a "definitely endangered language".

The Afroasiatic languages (also known as Afro-Asiatic, Afrasian, Hamito-Semitic, or Semito-Hamitic) are a language family (or "phylum") of about 400 languages spoken predominantly in West Asia, North Africa, the Horn of Africa, and parts of the Sahara and Sahel. Over 500 million people are native speakers of an Afroasiatic language, constituting the fourth-largest language family after Indo-European, Sino-Tibetan, and Niger–Congo. Most linguists divide the family into six branches: Berber (Amazigh), Chadic, Cushitic, Egyptian, Omotic, and Semitic. The vast majority of Afroasiatic languages are considered indigenous to the African continent, including all those not belonging to the Semitic branch (which originated in West Asia).

The five most spoken languages in the family are: Arabic (of all varieties), which is by far the most widely spoken within the family, with around 411 million native speakers concentrated primarily in West Asia and North Africa; the Chadic Hausa language, with over 58 million speakers in West Africa; the Cushitic Oromo language, with 45 million native speakers; the Semitic Amharic language, with 35 million; and the Cushitic Somali language with 24 million, all the latter three in the Horn of Africa. Other Afroasiatic languages with millions of native speakers include the Semitic Tigrinya, Tigre and Modern Hebrew, the Cushitic Beja, Sidama and Afar languages, the Berber languages (Shilha, Kabyle, Central Atlas Tamazight, Shawiya and Tarifit), and the Omotic Wolaitta language. Most languages of the non-Semitic branches (especially Chadic and Omotic) have far fewer speakers, and many Afroasiatic languages in Africa are vulnerable or endangered.
