The word 脆弱 is formed by combining two characters, each contributing a layer of meaning to create a unified concept. The first character, 脆, originally depicts "meat" (月, a form of 肉) that is easily broken, conveying brittleness or fragility. The second, 弱, is a pictograph of two feeble bows, doubling the idea of feebleness or weakness. Placed together, they visually and semantically reinforce each other to paint a vivid picture of something that is not just physically delicate but also inherently weak and easily damaged.
