Related Words
Size, volume, mass, bulk are terms referring to the extent or dimensions of that which has magnitude and occupies space. Size is the general word: of great size; small in size. Volume often applies to something that has no fixed shape: Smoke has volume. Mass, also, does not suggest shape, but suggests a quantity of matter in a solid body: a mass of concrete. Bulk suggests weight, and often a recognizable, though perhaps unwieldy, shape: the huge bulk of an elephant.
