No known speakers remain. Yuki has traditionally been considered related to Wappo (Powers 1877, Powell 1891, Kroeber 1906, 1911, 1925b, Elmendorf 1968, 1981, 1997), but Sawyer (1980) concludesthatsharedlexicalitemsaretoosimilartobecognatesandmorehkelythe resultofdiffusion.Therehave been anumberofhypotheses about deeperrelations between Yuki-Wappo and other North American languages. Kroeber 1907 noted both Hokan and Penutian traits in their structure. Sapir (1929) classified them asa separate branch of his Hokan-Siouan. Elmendorf noted similarities to Siouan and Yuchi (1963, 1964). Possible remote relations are discussed in section 6.3.
