When did Arizona get its name?

The word "Arizona" is derived from the Tohono O'odham word "alĭ ṣonak," which means "small spring" or "good place with a small stream." The name was given to the area in the early 18th century by Spanish explorers, who found the region to be a starkly beautiful and rugged desert with a scattering of small springs and streams. The name Arizona is one of the few Native American place-names adopted by the Spanish and used by the United States today.
