Which definition describes the noun 'sole'?

• A. The bottom part of a foot or shoe
• B. The bottom part of an object such as a golf club or a plow
• C. The top part of a tree
• D. A type of bread

Answer: (A)

Sole, as a noun in everyday use, most commonly refers to the bottom part of the body or a footwear item—the part that rests on the ground and supports you when you stand or walk. This is why the definition describing the bottom of a foot or a shoe fits best: it matches the familiar, everyday meaning people rely on when talking about feet, socks, or sneakers. The other options describe different things—top of a tree is its crown, a kind of bread isn’t named sole, and the bottom surface of some objects can be called a sole in more technical contexts—but those senses are less common in general vocabulary.
