放出
ほうしゅつ · houshutsu · JLPT N1 · noun
release
🚀 放 = let go/release + 出 = out: release out, emit
放 means let go or set free, as in 放手 (let go of a hand). 出 means out, as in 出口 (exit). Together they mean letting something go outward, such as releasing gas, light, or data.
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'.
出 — foot 止 emerging from enclosure 凵
出 is a pictograph showing a foot or plant stepping out of a hollow or enclosure, depicting the act of going forth. The original sense of 'coming out' or 'emerging' has remained stable since oracle bone script. It now broadly means 'to exit, go out, or produce.'
