Currency

Currency is the system of money used in a country. The currency system usually includes: the name of the money (Dollar, Euro, Yen, etc.), the units and values (1 dollar = 100 cents, 1 euro = 100 cents), the physical form (coins, notes, and sometimes digital money), the rules and organisations (central banks, laws, exchange systems). Currency allows people to buy, sell, and exchange goods and services. Each country usually has its own currency, and values can change when exchanged internationally. The term can also mean general acceptance of an idea or style (e.g., “That opinion has little currency today”). In daily life, “currency” mostly refers to money.
