悩む
なやむ · nayamu · JLPT N3 · verb-godan
to be troubled
🧠 悩 = heart 忄 + the right half of 脳 (brain): heart and head both churning
悩 shares its right side with 脳 (brain) but puts the heart radical 忄 where the body radical would be. Worry is the head and the heart troubled together. Sound hook: nayamu, nah, I am stuck on it.
