The word 有用 is formed by the direct and logical combination of two conceptual characters: 有 (yǒu), meaning "to have" or "there is", and 用 (yòng), meaning "use" or "utility". It is constructed by placing the state of possession before the object possessed, thereby visually and semantically creating the core idea of "having use" or "to possess utility". This formation follows a natural, descriptive thought process where the composite meaning emerges transparently from the sum of its parts.
