The word 打架 is formed by combining two characters: 打 (dǎ), meaning "to hit" or "to strike", and 架 (jià), which in this context evokes the image of a frame, structure, or posture of confrontation, as in two people locked in a physical struggle. Together, they create a compound where the action of "hitting" is directly applied to the scenario of a "confrontational clash", pictorially conveying the concept of a fight or brawl through this simple, cause-and-effect pairing.
