euro

The term 'euro' is a modern lexical invention, formally adopted in 1995. It is a straightforward clipping of the geographical name 'Europe,' derived from Europa of Greek mythology, whose name itself is of uncertain etymology, possibly from Greek elements meaning "broad-faced." The logic of the name is purely referential and geopolitical, designed to be a simple, recognizable symbol of European economic and political integration. Unlike words built from classical roots, its meaning is not compositional but is directly assigned to represent the single currency of the European Monetary Union.

This is a modern clipped form and a proper noun, not segmentable into classical morphemes with distinct senses. It is derived from the word "Europe."
