梏

A phono-semantic compound composed of:

木 — semantic component meaning “wood;”

告 — phonetic component indicating the sound (곡 / gù).

The character originally described a wooden restraint used to bind a prisoner’s hands.

Ancient Chinese punishments often used wooden restraints, which explains the 木 radical in the character.

Semantic development:

- wooden hand restraints used for prisoners;

- shackles or handcuffs;

- figuratively: restrictions or constraints.

The meaning expanded from physical restraints to metaphorical limitations.

梏 appears mainly in historical or literary contexts.

곡수 (梏手) — to bind someone’s hands; to put in handcuffs (classical usage)

The compound 桎梏 is the most common modern usage, meaning both literal shackles and figurative constraints such as social or ideological restrictions.
