About
The character 臬, structurally composed of 自 positioned above 木, etymologically derives from the concept of a wooden stake or marker used as a target or boundary. Its early meaning centered on a physical standard or limit, which over time extended to denote legal principles and abstract criteria, as seen in classical texts and compound words like 圭臬. This semantic shift from a concrete object to an authoritative norm illustrates its evolution in representing established rules or models.
