粥
かゆ · kayu · JLPT N1 · noun
porridge
🥣 Contains the rice radical 米, so it's a soft, watery rice dish: rice + gruel
The 米 radical on the left marks rice as the base. Japanese かゆ (kayu) is the same thing: rice cooked down in lots of water until soft.
粥 — bow 弓 + rice 米 + bow 弓
Originally an ideograph showing rice (米) cooking between rising vapor lines, depicted as two bow shapes (弓) representing steam. The character pictures grain simmering in water until soft. It primarily means rice porridge or congee (zhōu); the rare reading yù means to sell, a borrowed sense later written as 鬻.
