Currency that a government has declared to be legal tender, but which has no intrinsic value and is not backed by a physical commodity like gold or silver.
A monetary system where the value of money derives from government regulation, law, or decree (fiat), and public trust in the issuing authority, rather than from the material it is made of or its convertibility into a commodity.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'денежный указ'. The standard term is 'фиатные деньги' (fiatnyye den'gi) or 'декретные деньги' (dekretnyye den'gi).
- Do not confuse with the car brand 'Fiat'. In this context, it's pronounced 'fee-at' or 'fie-at'.
Common Mistakes
- Mispronouncing 'fiat' as 'fee-at' (UK/common) is acceptable, but 'fie-at' (US/less common) is also correct. The car is 'fee-at'.
- Using it as a countable noun (e.g., 'a fiat money'). It is generally non-count/uncountable, referring to a system or type of money.
