害

Phono-semantic compound:

宀 (집 면) — semantic element meaning “house,” indicating a context of confinement or domestic setting.

丯 (산란할 개) — phonetic component, giving the sound hài and implying “disorder” or “disturbance.”

口 (입 구) — an early component added to clarify the semantic relation to communication or expression.

According to the Shuowen Jiezi (《說文解字》), 害 combines 宀 “house” and 口 “mouth” to signify quarrels or harmful words arising within a household, producing the meaning “to injure” or “to do harm.”

Later analyses expanded this to a more abstract idea of destruction, obstruction, or injury.

In bronze inscriptions (金文 jinwen), the upper part resembles a covered vessel, possibly symbolizing containment or suppression, further reinforcing the notion of hindrance or harm.

危害 (위해) — to endanger, to harm

被害 (피해) — damage, suffering harm

害虫 (해충) — harmful insect, pest

害人 (해인) — to harm others

In extended meaning, 害 can also signify evil, calamity, or misfortune, as in 害心 (evil intent).

In classical philosophy, 害 represents harmful influence or obstruction to natural harmony.

In Confucian texts, it is often contrasted with 益 (benefit) — as in 損益之道 (the Way of loss and gain) — expressing the moral idea that to “cause harm (害)” is to act against benevolence and order.

In Buddhist texts, 害 is treated as one of the unwholesome actions (十惡業) — acts that cause suffering to living beings.

In modern East Asian languages, 害 remains central in ethical, legal, and medical vocabulary — from public harm (公害) to environmental damage (環境害).
