The kanji 唇 is a phono-semantic compound (形声文字, keisei moji). The left side is a radical called 口 (kuchi), meaning "mouth," indicating the semantic component (meaning). The right side is 辰 (shin), which is the phonetic component, contributing to the sound. The combination of the radical 口 and the phonetic component 辰 originally meant "lips" or "mouth rim." Over time, the meaning became more specifically associated with the fleshy part of the mouth.
