Seri is a language isolate spoken by about a thousand people in two villages on the coast of Sonora, Mexico. The native name for the language, cmiique iitom, means '(that) with which a Seri person speaks'. The language has also been called kunkaak, a version of the native name for the Seri people, comcaac. The origins of the name Seri are uncertain but are thought to come from another language in the region.
