Meaning & readings

chastise, attack, defeat, destroy, conquer

On’yomi トウ
Kun’yomi う.つ

Origin

The character 討 combines the word radical 言, meaning "speak" or "language," with 寸 on the right, which serves as a sound hint for pronunciation. The sense of "chastise" or "attack" developed from the idea of speaking out against someone—to criticize, denounce, or call out wrongdoing. Over time, this extended to the broader meanings of attacking, defeating, or destroying an enemy through forceful action. The 寸 component doesn't add to the meaning itself, but helps readers recognize how the character should be pronounced.
