About
The character 桎 is formed from the semantic component 木, representing wood, and the phonetic component 至. Its initial meaning was that of wooden shackles for the feet, directly tied to the wooden material implied by 木. From this concrete referent, the meaning extended to cover broader concepts of restraint, obstruction, or confinement. The character's construction with these components has historically linked it to ideas of impediment.
