隊

Phono-semantic compound:

阝 (언덕 부, “mound, place”) — semantic element, often denoting terrain, settlement, or grouping.

坠 (떨어질 추/퇴, “to fall, descend”) — phonetic element, giving the sound.

Originally indicated a group of people stationed at a place, especially military units gathered together. Over time, broadened to mean “any organized group” or “team.”

部隊 (부대) — military unit, troops

隊伍 (대오) — ranks, formation, line of troops

先鋒隊 (선봉대) — vanguard, spearhead force

救援隊 (구원대) — rescue team

球隊 (구대) — sports team

Shares semantic space with 軍 (군, army) but 隊 emphasizes an organized subdivision or team within a larger whole.
