Backyard is formed from "back" (from Old English "bæce", meaning at the rear) and "yard" (from Old English "geard", meaning an enclosed area or garden). The word "backyard" refers to an enclosed area or garden located at the rear of a house.
Think of the 'back' of a house where you have an 'enclosed area' or 'garden' — that's what a backyard is.
