heli-skiing

The word is a modern compound, a portmanteau of "helicopter" and "skiing," created in the mid-20th century to describe a specific adventure sport. "Helicopter" itself derives from Greek roots 'helix' (spiral) and 'pteron' (wing), describing the aircraft's rotating blades. "Ski" originates from Old Norse 'skíð', meaning a billet of wood or snowshoe. The fusion of these terms directly and transparently denotes the method of access (by helicopter) to pristine, off-piste terrain for the purpose of skiing.
