復旧
ふっきゅう · fukkyuu · JLPT N1 · noun
restoration
🔧 復 (return) + 旧 (old) = returning to the old state; fuku-kyuu sounds like 'fuck you' on the way back, so remember: restore = return to old
旧 — 丨 vertical stroke + 日 sun/day
旧 is the simplified form of 舊, which originally depicted an owl (萑) perched on a nest (臼) and was borrowed phonetically to mean 'old' or 'former.' The modern simplified shape combines 丨 with 日 (sun/day), suggesting days gone by. Today it means 'old,' 'former,' or 'used.'
