About
The character 臼 is a pictogram originating from the depiction of a mortar, a tool used for pounding grain, and its form has consistently represented a container with inward-sloping sides. Its primary meaning has always been the physical mortar, but over time it extended to denote any similar hollow or socket-like structure, such as in anatomical or mechanical contexts. Structurally, it exists as an independent character and also serves as a radical in compound characters, where it typically contributes the semantic element related to a mortar-like shape or cavity.
