It was not closely related to other known languages in the area, much of which are also poorly attested, and may have been a language isolate. A couple hundred words are preserved, collected in 1698, 1720, and 1828; in the 1880s, three lists were collected from non-Karankawa who knew some words.
Haida people The Haida ( , Haida: "X̱aayda, X̱aadas, X̱aad, X̱aat" ) are a nation and ethnic group native to, or otherwise associated with, Haida Gwaii and the Haida language. The language, which is an isolate language, has historically been spoken across Haida Gwaii and certain islands on the Alaska Panhandle, where it has been spoken for at least 14 000 years. Prior to the 19th century, Haida would speak a number of coastal First Nations languages such as Lingít, Nisg̱a'a and Sm'álgyax. After settlers' arrival and colonisation of the Haida through residential schools, few Haida speak X̱aayda/X̱aad kíl, though there are many efforts to revive the language.
