Context: The Alaska Native Language Center at the University of Alaska Fairbanks claims that at least 20 Alaskan native languages exist and there are also some languages with different dialects. Most of Alaska's native languages belong to either the Eskimo–Aleut or Na-Dene language families however some languages are thought to be isolates (e.g. Haida) or have not yet been classified (e.g. Tsimshianic). As of 2014[update] nearly all of Alaska's native languages were classified as either threatened, shifting, moribund, nearly extinct, or dormant languages.
