Moribund language in the context of "Chukotko-Kamchatkan languages"

Cypriot Arabic (Arabic: العربية القبرصية, Greek: Κυπριακά Αραβικά), also known as Cypriot Maronite Arabic or Sanna (Arabic: سانا, Greek: Σάννα), is a moribund variety of Arabic spoken by the Maronite community of Cyprus. Formerly speakers were mostly situated in Kormakitis, but following the Turkish invasion of Cyprus in 1974, the majority relocated to the south and dispersed, leading to the decline of the language. Traditionally bilingual in Cypriot Greek, as of some time prior to 2000, all remaining speakers of Cypriot Arabic were over 30 years of age. A 2011 census reported that, of the 3,656 Maronite Cypriots in Republic of Cyprus-controlled areas, none declared Cypriot Arabic as their first language.

Cherokee or Tsalagi (Cherokee: ᏣᎳᎩ ᎦᏬᏂᎯᏍᏗ, romanized: Tsalagi Gawonihisdi, IPA: [dʒalaˈɡî ɡawónihisˈdî]) is an endangered-to-moribund Iroquoian language and the native language of the Cherokee people. Ethnologue states that there were 1,520 Cherokee speakers out of 376,000 Cherokees in 2018, while a tally by the three Cherokee tribes in 2019 recorded about 2,100 speakers. The number of speakers is in decline. The Tahlequah Daily Press reported in 2019 that most speakers are elderly, about eight fluent speakers die each month, and that only five people under the age of 50 are fluent. The dialect of Cherokee in Oklahoma is "definitely endangered", and the one in North Carolina is "severely endangered" according to UNESCO. The Lower dialect, formerly spoken on the South Carolina–Georgia border, has been extinct since about 1900. The dire situation regarding the future of the two remaining dialects prompted the Tri-Council of Cherokee tribes to declare a state of emergency in June 2019, with a call to enhance revitalization efforts.

Around 200 speakers of the Eastern (also referred to as the Middle or Kituwah) dialect remain in North Carolina, and language preservation efforts include the New Kituwah Academy, a bilingual immersion school. The largest remaining group of Cherokee speakers is centered around Tahlequah, Oklahoma, where the Western (Overhill or Otali) dialect predominates. The Cherokee Immersion School (Tsalagi Tsunadeloquasdi) in Tahlequah serves children in federally recognized tribes from pre-school up to grade 6.

Ḥarsūsī (Arabic: لغة حرسوسية), natively known as Ḥersīyet (pronunciation in Harsusi: [ħʌrsiːjət]), is a Semitic language of Oman, spoken by the Harasis people. It is classified as a moribund language, with an estimated 600-1000 speakers in Jiddat al-Harasis, a stony desert in south-central Oman. It is closely related to Mehri.

Northumberland and Durham dialect, Northumbrian dialect, or in England North East dialect is any one of several traditional English dialects spoken in the historic counties of Northumberland and County Durham. The term Northumbrian can refer to the region of Northumbria but can also refer specifically to the county of Northumberland. This article focuses on the former definition and thus includes varieties from throughout the wider region, including County Durham.

The traditional Northumbrian dialect is a moribund older form of the dialect spoken in the area. It is closely related to Scots and Cumbrian and shares with them a common origin in Old Northumbrian.

Nǁng ([ᵑǁŋ]) or Nǁŋǃke is a almost extinct Tuu language spoken in South Africa. It is commonly known by the ambiguous name of its only spoken dialect Nǀuu (Nǀhuki); the ǀʼAuni name for the Nǀuu, ǂKhomani, is used by the South African government. Nǁng had been thought extinct and was no longer spoken on a daily basis when rediscovered, as the two dozen elderly speakers lived in different villages and the younger generations had shifted to the Khoekhoe language. As of October 2025, only one speaker of the Nǀuu dialect remains, the rest of the population having shifted to Khoekhoe and Afrikaans.
