altus

Altus is a term used in different contexts, most prominently in language and geography. In Latin, altus is an adjective meaning high, tall, or deep, with related forms such as altitudo (height) and altissimus (very high). The word appears in classical and ecclesiastical texts and has occasionally appeared in historical musical terminology to designate a high vocal part, roughly analogous to what is today called the alto.

In geography, Altus refers to a city in the southwestern United States. Altus, Oklahoma, is located mainly in Jackson County with a smaller portion extending into Harmon County. It serves as the county seat of Jackson County and is known for its connection to Altus Air Force Base, a major United States Air Force installation that has supported airlift and air refueling training and operations.

Altus also appears in contemporary usage as a surname or place name and can be encountered in various naming contexts beyond the Oklahoma city. As a given name, it is less common but has appeared in some cultures and historical records. The diverse uses of Altus reflect its Latin roots and its adoption into modern nomenclature across places and institutions.
