Etymology

A diamond: small  to big  to small 

About

is a noun for a traditional spinning top (a spindle-shaped toy). It is built by vertically stacking (small), (big), and another , creating a diamond silhouette (small → big → small). This arrangement directly diagrams the toy's wide middle and pointed ends. Unlike the majority of Chinese characters, which combine a semantic radical and a phonetic component, is purely pictographic, using the geometric relationship of its parts to sketch an object's form. The result is a rare example of a character whose internal structure functions as a literal diagram of the thing it names.
