Etymology: Chihuahuan is an adjective formed from "Chihuahua," the name of a Mexican state and its capital city, with the suffix "-an" meaning "of or relating to." So a Chihuahuan desert is one found in that region, and the word has no older history in English beyond that. The place name itself comes from the Indigenous Nahuatl-speaking peoples of the area, though its exact meaning is uncertain; a commonly cited but unconfirmed explanation links it to a word for "dry, sandy place." The adjective is used mostly in scientific and geographic contexts. The Chihuahuan Desert, which spreads across northern Mexico and into parts of Texas, New Mexico, and Arizona, is its most familiar application, and the same pattern gives us other regional adjectives like "Ohioan" and "Alaskan."
