The word 无限 is formed by combining two conceptual characters: 无, which means "without" or "lack of", and 限, which means "boundary", "limit", or "restriction". Their combination is purely ideographic, creating a new, compound concept where the meaning of the first character directly modifies the second. Thus, 无限 literally and conceptually means "without-boundary", evolving to express the abstract idea of "limitless", "infinite", or "boundless".
