Underfoot → It is formed from "under" (from Old English "under", meaning beneath) and "foot" (from Old English "fōt", meaning the lower extremity of the leg). The word "underfoot" describes something that is beneath one's feet or on the ground.
Think of something being 'beneath' ('under') your 'feet' — that's what underfoot means.
