"Semat" is an alternate name for the Plains Apache tribe.
This was their name in the language of their Kiowa allies.
Although the Kiowa and the Plains Apache normally had very friendly
relations, hosting each other at ceremonies and even intermarrying,
the word Semat means "stealers" in Kiowa.
Some Apache people believe that this name may have referred to horse raiding,
an activity considered to be a test of bravery among Plains Indian tribes,
rather than an insult about being thieves.
