The word 攻击 is formed by combining two characters, 攻 and 击, each contributing a similar core meaning related to assault. 攻 carries the notion of an offensive action, like launching an assault on a city or stronghold, while 击 conveys the idea of striking or hitting a target. Placed side-by-side, they create a single, powerful concept where their individual meanings reinforce and intensify each other, visually and semantically merging into the comprehensive idea of "to attack".
