怪 — heart radical 忄 + 圣 (phonetic)
怪 combines the heart radical 忄, suggesting feelings or mental states, with 圣 serving as a phonetic component. The original sense relates to something strange or uncanny that provokes wonder or unease in the heart. It now broadly means 'strange,' 'odd,' or 'to blame.'
