The word 逮捕 (dàibǔ, meaning "to arrest") is formed through the combination of two characters that both independently convey the core idea of catching or seizing. The first character, 逮, originally depicted a hand catching something, carrying the sense of reaching and apprehending. The second, 捕, visually and conceptually represents a hand using a tool or action to seize or capture. When placed together, they do not create a metaphorical or abstract meaning but rather reinforce and specify each other, merging into a single, more definitive concept of capturing and detaining a person under legal authority.
