A currency (from Middle English curraunt, meaning in circulation) refers to money in any form when in actual use or circulation, as a medium of exchange, especially circulating paper money. This use is synonymous with banknotes, or (sometimes) with banknotes plus coins, meaning the physical tokens used for money by a government.

A somewhat more general definition in economics is that a currency is a system of money (monetary units) in common use, especially in a nation. Under this definition, British pounds, U.S. dollars, and European euros are different types of currency, or currencies. Currencies in this definition need not be physical objects, but as stores of value are subject to trading between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in the sense used by foreign exchange markets, are defined by governments, and each type has limited boundaries of acceptance.

An even more general use of the word currency is anything that is used in any circumstances as a medium of exchange. In this use currency is a synonym for the concept of money.

Famous quotes containing the word currency:

    Money is the worst currency that ever grew among mankind. This sacks cities, this drives men from their homes, this teaches and corrupts the worthiest minds to turn base deeds.
    Sophocles (497–406/5 B.C.)

    Common experience is the gold reserve which confers an exchange value on the currency which words are; without this reserve of shared experiences, all our pronouncements are cheques drawn on insufficient funds.
    René Daumal (1908–1944)

    Both of us felt more anxiety about the South—about the colored people especially—than about anything else sinister in the result. My hope of a sound currency will somehow be realized; civil service reform will be delayed; but the great injury is in the South. There the Amendments will be nullified, disorder will continue, prosperity to both whites and colored people will be pushed off for years.
    Rutherford Birchard Hayes (1822–1893)
