Linguistic issues

The formal titles of the currency are euro for the major unit and the cent for the minor (one hundredth) unit and for official use in most eurozone languages;according to the ECB, all languages should use the same spelling for the nominative singular. This may contradict normal rules for word formation in some languages; e.g., those where there is no eu diphthong. Bulgaria has negotiated an exception; euro in the Cyrillic alphabet is spelled as eвро (evro) and not eуро (euro) in all official documents. The European Commission's Directorate-General for Translation states clearly that the plural forms euros and cents should be used in English.
