送金
そうきん · soukin · JLPT N1 · noun
remittance
💸 送 (sou) = send + 金 (kin) = money, so 送金 = sending money (remittance)
送 means send and 金 means money, and the compound names the act of sending money to someone else. The reading kin here is the on-yomi used in compounds like 送金, not the kun-yomi kane.
送 — 辶 (walk) + 关 (simplified from 灷, fire/torch)
Originally depicted hands holding a torch to escort someone on a journey, combined with the 'walk' radical 辶. The right side 关 is a simplification of an older form showing fire being carried. The core meaning evolved from 'escort/see off' to the broader sense of 'send' or 'give as a gift.'
金 — roof 亼 + two dots (metal nuggets) + earth 土
Originally a pictograph of metal nuggets buried in the earth beneath a covering, with the two dots representing pieces of ore. It first meant 'metal' broadly, then narrowed to 'gold' as the most precious metal, and by extension 'money'.
