Meaning
憎 (ZŌ, niku.mu) means to hate, detest, or abhor — a strong, visceral aversion aimed at a person or thing. Unlike milder words for dislike, 憎 implies something deep-rooted and enduring. It appears across literature, news, and everyday conversation whenever feelings of enmity or animosity surface.
Structurally, 憎 is a semantic-phonetic compound with two parts. Left side: the radical 忄 (risshinben), a compact form of 心 (kokoro, 'heart' or 'mind') — a signal that this character belongs to the world of emotions. Right side: 曽 (SOU/ZOU), which supplies the pronunciation and evokes something layered or built up over time. Together, they suggest hatred as a feeling that accumulates in the heart — not a flash of anger, but something that settles in and stays.
At 14 strokes, 憎 sits in the mid-complexity range for Jōyō kanji. Its N2 designation means it appears in JLPT reading passages and real-world texts — expect to encounter it in crime fiction, editorials, and emotionally charged dialogue.

Memory Tip
Split the character in two. Left side: 忄 (risshinben), the heart radical — always a marker of emotion. Right side: 曽 (SOU/ZOU), which gives the reading and evokes something that accumulates, layer by layer.
Picture a heart quietly collecting resentment over years — not a sudden rage, but a feeling that compounds until it becomes hatred. That slow buildup is exactly what 憎 describes.
