What Is the Plural of Euro?
The Quick Answer
The plural of "euro" is "euro" or "euros." In everyday English, "euros" is now the most common plural. (If you're referencing or editing EU legal documentation, copy the version in the original.)The plural of "euro" is most commonly written as "euro" in European Union (EU) legislation, even though this is at odds with the standard way of forming plurals in English. As a consequence of the plural "euro" being embedded in the early legal documentation that saw its launch, "euro" was widely used as the plural in the years after 2002, when most EU countries adopted the euro. These documents provided the precedent for writers searching for an answer to "what is the plural of euro?".
However, as the "euro" became embedded in daily life, less conscious thought was given to its plural, and the plural "euros" quickly overtook "euro" because "euros" sounds far more natural to native English speakers.
EU guidance now recommends that "euros" be used unless editing or quoting the original EU documentation that employs "euro."
