The euro has again become the subject of heated debate - but this time the controversy is over its plural form.
While some regard euros and cents as the logical English plural of the names of the notes and coins, others believe euro and cent to be the correct version. So who's right?
Mr Philip Hamell, head of the Euro Changeover Board of Ireland, some people get very worked up over the issue, but there is no right or wrong answer.
When drafting the laws governing the new currency, the EU authorities used euro and cent as the plural, mainly to avoid having different plural forms in national languages.
But Mr Hamell points out that that there is nothing to stop people from adding an "s" to create the plural if they so choose. "It is not wrong. We prefer to say euro and cent because that's what you see on the notes and coins but there is no law saying you can't put an 's' on the end."
