Wiyot (also Wishosk) is an extinct Algic language. The Algic languages are an indigenous language family of North America. ...

Concerning etymology of Wiyot (a.k.a. Wishosk)

This below is from Campbell (1997):

"Wiyot is from wíyat, the native name for the Eel River delta, which also referred to one of the three principal groups of Wiyots (Elsasser 1978:162).

"The connection of Wiyot and Yurok in northern California (which together were formerly called Ritwan, after Dixon and Kroeber's [1913] grouping of the two as one of their more remote Californian stocks) with Algonquian was first proposed by Sapir (1913) and was quite controversial at that time (see Michelson 1914, 1915; Sapir 1915a, 1915b; see also Chapter 2), but the relationship has subsequently been demonstrated to the satisfaction of all (see Haas 1958; Teeter 1964a; Goddard 1975, 1979, 1990). Before 1850 the Yurok lived on the lower Klamath River. The Wiyot (earlier called Wishosk) lived in the Humboldt Bay area, in the redwood belt; the last fully fluent speaker died in 1962 (Teeter 1964b). Many scholars have commented that although Wiyot and Yurok are neighbors in northern California, they seem not to have a closer relationship with each other than either has with Algonquian...." (Campbell 1997:152).
