圈套
quān tào · HSK 7
trap
🪤 圈 circle/loop + 套 noose/cover = a loop that covers you: a snare
圈 is a ring or enclosure; 套 is a cover or noose that slips over something. Together they name the looped cord of a trap, hence trick or snare you get caught in.
圈 — enclosure 囗 + juàn 卷 (phonetic)
A semantic-phonetic compound: the outer 囗 ('enclosure') gives the meaning of a ring or pen, while the inner 卷 supplies the sound. Originally it referred to a fenced enclosure for animals, then broadened to mean any circle, ring, or social circle.
套 — big 大 + long 镸 (long hair)
套 combines 大 (big) over 镸 (long), suggesting something large and elongated that wraps or covers. The original sense was a covering or sheath that fits over something else, later extending to 'set,' 'cover,' or 'to slip over.' Modern uses like 一套 (a set) and 手套 (gloves) preserve this idea of an enclosing wrapper.
