What 砨 means
砨 names a precious stone in the compound 砥砨.
史记, a Chinese history, names 砥砨 among the Zhou royal house’s treasures, beside 结绿, 悬黎 and 和璞. The passage likens an overlooked gem to talent rulers miss. The text 戰國策 from the Warring States period preserves the earlier spelling 砥厄; a later dictionary quotes the Song dynasty rhyme book 集韻.
Historical and specialist; its clearest context is the compound 砥砨.
