A shape designed to create lift when air flows over it, commonly used in aircraft wings and other vehicles to help them fly.
The engineer designed a new aerofoil to improve the aircraft's performance.
Aerofoil → It is formed from "aero-" (from Greek "aēr", meaning air) and "foil" (from Old French "foille", meaning leaf or sheet). The word "aerofoil" refers to a structure designed to generate lift when moving through air, resembling a leaf or sheet in shape.
Think of 'air' ('aero-') and a 'sheet' ('foil') that helps lift things up when they move through the air.
