The word 袭击 is formed by combining two characters, each contributing a core meaning to create a new, more specific concept. The first character, 袭 (xí), carries the inherent idea of a raid or a surprise approach, often implying repetition or following a pattern. The second character, 击 (jī), means to hit or strike with force. When placed together, they semantically merge to depict the action of a striking raid or a forceful surprise attack, where the method (stealthy/sudden approach) and the action (violent strike) are conceptually fused into a single term.
