Variants like the apparently popular Lady Grey â it's got orange in it â and this new Earl Grey Bergamot City, or whatever it's called, are not really needed. (The Earl Grey-flavoured Kit-Kat was, if Wikipedia is to be believed, fortunately confined to the Japanese market.)
A currency (from Middle English: curraunt, in circulation, from Latin: currens, -entis) in the most specific use of the word refers to money in any form when in actual use or circulation as a medium of exchange, especially circulating banknotes and coins.ther definitions of the term currency are discussed in their respective synonymous articles banknote, coin, and money. The latter definition, pertaining to the currency systems of nations, is the topic of this article.
A more general definition 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 examples of currency. These various currencies are stores of value, and are traded between nations in foreign exchange markets, which determine the relative values of the different currencies.
