The word 巨人 is formed by directly combining two characters: 巨, meaning "huge" or "gigantic", and 人, meaning "person" or "human". It creates a literal, conceptual compound where the attribute of enormous size is applied to the entity of a person, resulting in the core meaning of a "giant" or a colossally large human figure. This formation visually and notionally stacks the idea of scale onto the basic form of a human being.
