冬眠
とうみん · toumin · JLPT N1 · noun
hibernation
🐻🌰 冬 (winter) + 眠 (sleep): winter sleep, as bears and hamsters do
冬 means winter and 眠 means sleep, so 冬眠 literally means sleeping through winter. Japanese 'tou-min' also sounds like 'toe-min', a reminder that the toes of hibernating animals go numb with cold.
