Why does 回 look like this?
The character looks like a smaller square inside a larger square (囗, the 'enclosure' radical). It depicts the idea of something revolving or returning to its origin, just like an object circling back to its center. It's one of the simplest and most visual ways to represent the concept of 'coming back'!
