Underwing → It is formed from "under" (from Old English "under", meaning beneath or below) and "wing" (from Old English "wenge", meaning wing or fin). The word "underwing" refers to the part of a bird's wing that is located beneath the upper wing surface.
Think of something that is 'beneath' ('under') the 'wing' — that's why underwing refers to the underside of a bird's wing.
