Language death in the context of Language survey

Latin (lingua Latina or Latinum) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally spoken by the Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, including English, having contributed many words to the English lexicon, particularly after the Christianisation of the Anglo-Saxons and the Norman Conquest. Latin roots appear frequently in the technical vocabulary used by fields such as theology, the sciences, medicine, and law.

By the late Roman Republic, Old Latin had evolved into standardised Classical Latin. Vulgar Latin refers to the less prestigious colloquial registers, attested in inscriptions and some literary works such as those of the comic playwrights Plautus and Terence and the author Petronius. While often called a "dead language", Latin did not undergo language death. Between the 6th and 9th centuries, natural language change in the vernacular Latin of different regions evolved into distinct Romance languages. After the fall of the Western Roman Empire, Latin remained the common language of international communication, science, scholarship and academia in Europe into the early 19th century, by which time modern languages had supplanted it in common academic and political usage.

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."

Umbrian is an extinct Italic language formerly spoken by the Umbri in the ancient Italian region of Umbria. Within the Italic languages it is closely related to the Oscan group and is therefore associated with it in the group of Osco-Umbrian languages, a term generally replaced by Sabellic in modern scholarship. Since that classification was first formulated, a number of other languages in ancient Italy were discovered to be more closely related to Umbrian. Therefore, a group, the Umbrian languages, was devised to contain them.

Avestan (/əˈvɛstən/ ə-VESS-tən) is the liturgical language of Zoroastrianism. It belongs to the Iranian branch of the Indo-European language family and was originally spoken during the Avestan period (c. 1500 – 400 BCE) by the Iranians living in eastern Greater Iran as evidenced from names in Avestan geography.

After Avestan became extinct, its religious texts were transmitted orally, then collected and put into writing during the Sasanian period (c. 400 – 500 CE). The extant material falls into two groups: Old Avestan (c. 1500 – 900 BCE) and Younger Avestan (c. 900 – 400 BCE). The immediate ancestor of Old Avestan was the Proto-Iranian language, a sister language to the Proto-Indo-Aryan language, with both having developed from the earlier Proto-Indo-Iranian language. As such, Old Avestan is quite close in both grammar and lexicon to Vedic Sanskrit, the oldest preserved Indo-Aryan language.

An endangered language or moribund language is a language that is at risk of disappearing as its speakers die out or shift to speaking other languages. Language loss occurs when the language has no more native speakers and becomes a "dead language". If no one can speak the language at all, it becomes an "extinct language". A dead language may still be studied through recordings or writings, but it is still dead or extinct unless there are fluent speakers left. Although languages have always become extinct throughout human history, endangered languages are currently dying at an accelerated rate because of globalization, mass migration, cultural replacement, imperialism, neocolonialism and linguicide (language killing).

Language shift most commonly occurs when speakers switch to a language associated with social or economic power or one spoken more widely, leading to the gradual decline and eventual death of the endangered language. The process of language shift is often influenced by factors such as globalisation, economic authorities, and the perceived prestige of certain languages. The ultimate result is the loss of linguistic diversity and cultural heritage within affected communities. The general consensus is that between 6,000 and 7,000 languages are currently spoken. Some linguists estimate that between 50% and 90% of them will be severely endangered or dead by the year 2100. The 20 most common languages, each with more than 50 million speakers, are spoken by 50% of the world's population, but most languages are spoken by fewer than 10,000 people.

Language revitalization, also referred to as language revival or reversing language shift, is an attempt to halt or reverse the decline of a language or to revive an extinct one. Those involved can include linguists, cultural or community groups, or governments. Some argue for a distinction between language revival (the resurrection of an extinct language with no existing native speakers) and language revitalization (the rescue of a "dying" language).

Languages targeted for language revitalization include those whose use and prominence is severely limited. Sometimes various tactics of language revitalization can even be used to try to revive extinct languages. Though the goals of language revitalization vary greatly from case to case, they typically involve attempting to expand the number of speakers and use of a language, or trying to maintain the current level of use to protect the language from extinction or language death. Language revitalization can face significant barriers, not the least of which can come from governments, such as a general lack of support or funding for the projects, or a system that may actively repress the minority language. Other barriers could be a lack of speakers, a lack of relevant teaching material, or vocabulary loss.

The Istro-Romanians (Istro Romanian: rumeri or rumâri) are a Romance ethnic group native to or associated with the Istrian Peninsula. Historically, they inhabited vast parts of it, as well as the western side of the island of Krk until 1875. However, due to several factors such as the industrialization and modernization of Istria during the socialist regime of Yugoslavia, many Istro-Romanians emigrated to other places, be they Croatian cities such as Pula and Rijeka or places such as New York City, Trieste and Western Australia. The Istro-Romanians dwindled severely in number, being reduced to eight settlements on the Croatian side of Istria in which they do not represent the majority.

It is known that the Istro-Romanians are not descendants of a historical Roman population native to Istria, since the differences between the Istro-Romanian language and the geographically close, now extinct Dalmatian language, are notable. Additionally, similarities to Transylvanian Romanians and Timok Vlachs suggest that Istro-Romanians may originate from areas west of Romania or Serbia. Although it is not known exactly how and when, the Istro-Romanians settled in Istria, where they would remain for centuries until they began to assimilate. Even now, with several associations and projects aiming to preserve their culture and with the support from both the Croatian and Romanian governments, the Istro-Romanians are not officially recognized as a national minority.

Kanoê or Kapishana is a nearly extinct language isolate of Rondônia, Brazil. It is nearly extinct, with only 5 speakers in a population of about 319 Kanoê people. The Kapishana people now speak Portuguese or other indigenous languages from intermarriage. The language names are also spelled Kapixana, Kapixanã, and Canoé, the last shared with Awa-Canoeiro. The Kanoê people, although disperse in the southeastern part of the state of Rondônia, live mainly along the Guaporé River.

The Kalinago language, also known as Island Carib and Igneri (Iñeri, Inyeri, etc.), was an Arawakan language historically spoken by the Kalinago of the Lesser Antilles in the Caribbean. Kalinago proper became extinct by about 1920 due to population decline and colonial period deportations resulting in language death, but an offshoot survives as Garifuna, primarily in Central America.

Despite being known as Island Carib, the language was not closely related to the Carib language of the mainland Caribs. Instead, it appears to have been a development of the Arawakan language spoken by the islands' earlier Igneri inhabitants, which incoming Caribs adopted in the pre-Columbian era. During the French colonial period, Carib men also spoke a Cariban-derived pidgin amongst themselves.
