What does “fiat currency” mean?

Government-issued legal tender not backed by a physical commodity such as gold or silver.

Etymology

Fiat is Latin for "let it be done", a form of the verb fieri, "to be made, to come about". English took it as a noun for an authoritative order or decree. Fiat money, or fiat currency, is money that has value because a government declares it legal tender, not because it can be exchanged for gold or silver. Currency comes from Latin currere, "to run", and first referred to the fact of circulating from hand to hand.
