Let’s play a quick game: Read the title of this blog post aloud. How did you read it? “A coffee costs two euros” or “A coffee costs two euro”? Here’s my guess: If you’re American, British, or Portuguese, you probably said “two euros”. If you’re German or Italian, you probably said “two euro”. The nice thing about this game is that everyone wins. The correct plural of euro is euro or euros, depending on whom you ask or what dictionary you consult.
One euro, two euro, two euros
In most of the English-speaking world, euros is the commonly used plural of euro. For native English speakers, it’s natural to add -s to form the plural—just like the plural of dollar is dollars and the plural of pound is pounds. But when speaking English, a German or an Italian is likely to use the plural euro. Some native English speakers use the plural euro as well. Also, if you look at a 50-euro note, it has “50 euro” written on it. Does that mean the “official” plural of euro is euro? The answer lies in the history of this currency.
