Halfpipe → The word is formed from "half" (from Old English "healf", meaning one of two equal parts) and "pipe" (from Old English "pipa", meaning a tubular object). Together, these parts describe a structure that is half of a full pipe, typically used in sports for performing tricks.
Think of 'half' as one of two equal parts and 'pipe' as a tubular structure — a halfpipe is literally a half of a tubular ramp used in sports.
