Language isolate

Language that has no demonstrable genetic relationship with other languages

A language isolate, sometimes called an isolated language, is a language that has no demonstrable genealogical relationship with any other language. That is, an isolate is a language family that only contains one member. Basque in Europe, Ainu (if counted as a single language) and Burushaski in Asia, Sandawe and Hadza in Africa, Haida and Zuni in North America, Kanoê and Trumai in South America, Tiwi and possibly Porome in Oceania are examples of language isolates, as too are well attested extinct languages such as Sumerian and Elamite.
