Origin of Euro
noun plural -os
name for the basic monetary unit of a pan-European currency, from 1996.
The common currency used in eleven countries of the European Union (Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, The Netherlands, Portugal, and Spain). The euro became the official currency of these nations in 1999, but nations were not obliged to phase out their existing currencies until 2002. The expectation is that introduction of the euro will stimulate cross-border investment by eliminating fluctuating exchange rates.
