About
The character "柙" is structured with the semantic component "木" representing wood and the component "甲" which phonetically suggests "armor" or "shell", indicating a wooden protective enclosure. Its original meaning was a wooden cage or pen specifically for confining animals, notably tigers, as documented in early texts. Over time, the term expanded to refer more generally to any wooden box or restraining device, with the components continuing to evoke the idea of a wooden shell used for containment.
