Origin

The character 椎 combines wood (木) on the left with a bird or small creature (隹) on the right. The original meaning likely comes from a type of tree—the chinquapin—which has a distinctive shape. Over time, the character's meanings expanded: a mallet or club is a wooden tool shaped somewhat like a tree trunk, and the spine of the body resembles a wooden pole or stake running through it. The bird component's role here is less clear and may reflect an older formation logic that has become obscured through historical changes in how the character was understood.
