From Latin 'monēta' (mint, coined money), named after Juno Monēta — the goddess whose temple housed Rome's coin mint. 'Monēta' from 'monēre' (to warn), from PIE *men- (to think). The same root gives us mint, mental, memory, monitor, and mind.
A current medium of exchange in the form of coins and banknotes; assets and property.
From Old French 'moneie' (money, coin, currency), from Latin 'monēta' (mint, coined money, a place where coins are struck), from 'Monēta,' an epithet of the goddess Juno. The Romans minted their coins in the temple of Juno Monēta on the Capitoline Hill, and the building's name transferred to the product made there — a classic metonymy. The epithet 'Monēta' likely derives from 'monēre' (to warn, to advise, to remind), from PIE *men- (to think), as Juno was venerated as a divine counsellor and warner. The word thus preserves a remarkable chain: a goddess's title → the temple
English 'money' and 'mint' are doublets — both from Latin 'monēta', borrowed at different times via different routes. 'Money' came through French; 'mint' came through Old English from the same Latin word. And the PIE root *men- (to think) connects money to mind, mental, memory, monitor, and monument — all things that help you remember.
