Shash is the word for bear in Diné bizaad (Navajo language).
Shashtsoh is grizzly bear.
Shash łizhinii is black bear.
The "spelling" system was developed in the 1940s.
The L with a line through it is a sound that is like one in Welsh. You put your tongue in the L position and blow out around the sides.
The bear does not really "stand" for anything in the traditional Navajo religion. There are bears in some traditional stories and a clan and a mountain that has the bear (or it's spirit) as a protector but the bear is not really a big part of traditional belief. It is important in one ceremony, the Mountain Way chant. Hunting bear or eating it is considered taboo. Traditional Navajo do not wear bear claws or parts.
