wickiup
A domed hut, similar to a wigwam, used by some seminomadic Native American tribes, particularly in the southwestern and western United States.
They say his real name is Cimarron Seven, of the Choctaw Indian family of Sevens; he was raised in a tepee; a wickiup had been his bedroom, a blanket his robe.
Where it comes from
Wickiup-like structures were built by many Native American peoples throughout the Southwestern United States, and terms similar to wickiup are present "among Native Americans in Arizona, New Mexico, Utah, Idaho, and California", but the source of the word appears to be Fox wîkiyâpi (“house”). Alternatively, it may be a variant of wikiwam (“wigwam”). Either way, its ultimate origin is the Proto-Algonquian root *wi·kiwa·ʔmi (“house”). Doublet of wigwam.
