heat-trapping

The term 'heat-trapping' is a modern English compound adjective, transparently constructed from native Germanic elements. The first element, 'heat', derives from the Old English concept of warmth and high temperature. The second element, 'trap', originates from the Old English word for a snare or device for catching and holding something. The suffix '-ing' converts the verbal action into a descriptive adjective. Thus, the literal logic of "catching and holding heat" directly and vividly describes the physical property, most commonly applied to greenhouse gases in the atmosphere which absorb and retain infrared radiation.
