About
The character 痦 is a phono-semantic compound denoting a mole or dark skin spot. It combines the radical 疒, indicating a bodily condition, with the phonetic component 吾 (wú) inside, which provides the pronunciation. This structure creates a specific medical term for pigmented skin growths. It appears most commonly in the word 痦子 (wùzi), the standard term for a mole. The meaning remains concrete and dermatological, derived directly from its components.
