air-conditioned
UK: ˈeə kənˌdɪʃənd | US: ˈer kənˌdɪʃənd
adj. (of a room or building) cooled or heated by a system that controls the temperature and humidity of the air
The word "air-conditioned" combines "air" (from Old French air, Latin aer, meaning "atmosphere") and "condition" (from Latin condicio, meaning "agreement" or "state," later evolving to mean "to regulate"). The suffix "-ed" turns the phrase into an adjective, describing a space where air is artificially regulated. The term emerged in the early 20th century with the advent of climate control technology, reflecting a literal "conditioning" of air for comfort.
