放肆
fàng sì · HSK 7
presumptuous
😤 fàng (let loose) + sì (four/reckless) = unleash recklessness
放 means release or let go. 肆 originally meant a shop or market stall but evolved to mean unrestrained or wanton. Together: letting loose without any restraint — acting shamelessly impudent.
放 — 方 (square/phonetic) + 攵 (rap/strike radical)
放 is a semantic-phonetic compound: 方 supplies the sound and 攵 (a hand holding a stick) supplies the meaning of striking or driving away. The original sense was to banish or drive out, which broadened over time to 'release', 'let go', and 'put down'.
