憎嫉 is a compound verb meaning 'to detest and be jealous of' — it expresses a strong, negative emotional blend of hatred and envy. The first character 憎 (zēng) means 'to hate' or 'to abhor', often implying moral disapproval or deep aversion. The second character 嫉 (jí) means 'to be jealous' or 'envious', typically directed at someone’s advantages, success, or qualities. Together, they intensify each other: the jealousy isn’t mild envy but one laced with resentment and hostility.

This word is formal and literary, commonly found in classical texts, modern essays, or psychological descriptions — rarely in casual speech. It often describes toxic interpersonal dynamics, such as resentment toward a colleague’s promotion or a peer’s talent. Because both characters carry strong negative weight, 憎嫉 conveys deeper malice than either term alone, suggesting emotional conflict that may motivate harmful behavior.
