1) Ute. The word "Ute" comes from the Spanish spelling of a Shoshonean word that means "mountain dweller." The Utes were Indigenous peoples who historically inhabited much of the present-day U.S. states of Utah, Colorado, and New Mexico.
2) Atim. This part of the county's name is believed to be derived from a Timpanogos word meaning "highland country" or "hill people." The Timpanogos were another Indigenous group who resided in the Utah Valley region.
Thus, the name "Utah County" represents a blend of these Indigenous terms, acknowledging the historical presence and significance of the Ute and Timpanogos peoples in the region.
