Meaning & readings

same, agree, equal

On’yomi ドウ
Kun’yomi おな.じ

Origin

This character combines the idea of enclosure with the concept of sameness. The box-like frame on the outside (冂) represents a container or boundary, while the horizontal line and smaller box inside (一 and 口) show things placed together within that same space. When multiple things occupy the same enclosed area, they share the same place and are therefore equal or identical. Over time, this visual idea of things grouped together in one container came to mean "same" or "agree."
