winter
冬 centers on the coldest season: winter.
冬 is a pictograph of a knotted rope or cord, originally representing the end of the year. The modern form adds 冫 (ice) to emphasize the cold of winter.
The top 夂 looks like a person walking, and the bottom 冫 is ice. Picture someone trudging through ice and snow: it must be winter.
For トウ, imagine a toe freezing in the winter cold: toe -> トウ, and the ice 冫 makes your toe numb.
