fast-moving
UK: ˌfɑːst ˈmuːvɪŋ | US: ˌfæst ˈmuːvɪŋ
adj. changing or progressing rapidly
adj. characterized by quick movement or action
The word "fast-moving" is a compound adjective formed by combining "fast" (from Old English fæst, meaning "firm" or "quick") and "moving" (from Old English mōvian, meaning "to set in motion"). Over time, "fast" evolved to emphasize speed, while "moving" retained its core sense of motion. The compound logically merges these ideas to describe something that progresses or changes swiftly.
