The word 亲吻 (qīnwěn), meaning "to kiss", is formed by combining two characters that each contribute a key aspect of the action. The first character, 亲 (qīn), conveys a sense of closeness, intimacy, and affection. The second character, 吻 (wěn), specifically means "lips" or "mouth". Therefore, the compound visually and conceptually fuses the idea of intimate affection with the physical act involving the lips, creating a direct picturing of the gesture itself.
