桎

A phono-semantic compound composed of:

木 — semantic component meaning “wood;”

至 — phonetic component indicating the sound (질 / zhì).

The character originally described wooden restraints used to bind prisoners’ feet.

Ancient punishment systems often used wooden restraints, which explains the 木 radical.

Semantic development:

- wooden fetters placed on prisoners’ feet;

- shackles or restraints;

- figuratively: oppression, restrictions, limitations.

The meaning expanded from physical restraints to symbolic constraints.
