In linguistics, language death occurs when a language loses its last native speaker. By extension, language extinction is when the language is no longer known, including by second-language speakers, when it becomes known as an extinct language. A related term is linguicide, the death of a language from natural or political causes.
The disappearance of a minor language as a result of the absorption or replacement by a major language is sometimes called "glottophagy".
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."
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.
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.
