Etymology
Nacelle comes from an old French word nacelle and the Latin root navis, which means 'ship' or 'small boat' and is the same root as navy. A helpful way to remember it is to imagine a little boat attached to the airplane: a nacelle is a boat-like cover fixed to the wing or body that holds the engine, so the origin explains its shape and purpose.
