怪しい

あやしい · ayashii · JLPT N2 · i-adj

suspicious

🔍 怪 = strange (as in 怪物 monster) + しい = strange-seeming, so suspicious

怪 means strange or mysterious, as in 怪物 (monster) and 怪談 (ghost story). Add the adjective ending しい and you get 'strange-seeming': something off enough to be suspicious or dubious. Sound hook: aya-SHII, as in 'eye, eh? shh!'

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.'
