礁 is a phono-semantic compound. The radical 石 (stone) indicates its rocky nature, while 焦 (jiāo, meaning burnt or scorched) provides phonetic clues and suggests how reefs often appear weathered or darkened like scorched rock. Together, they depict a reef as a hardened, rock-like formation in the sea.
💡 Memory Tip: Picture a stone (石) reef that has been scorched (焦) black by the blazing sun and salt spray.
