矯

A phono-semantic compound:

矢 (arrow) — semantic component, indicating straightness (an arrow must be straight)

喬 (교) — phonetic component, supplying the sound (교 / jiǎo)

The original image suggests straightening something bent, like aligning an arrow—hence to correct or rectify.

Semantic development:

- straighten physically — correcting bent shape

- rectify faults — moral or behavioral correction

- technical correction — medical, orthodontic, or linguistic usage

교정 (矯正) — correction; rectification (medical, legal, linguistic)

교형 (矯形) — correction of form; straightening the body

교자세 (矯姿勢) — posture correction

교과 (矯過) — to correct faults (literary)

Compared with 正 (correct, right), 矯 emphasizes active correction of something already wrong or bent.
