Official practice for English-language EU legislation (not necessarily in national legislation) is to use the words "euro" and "cent" as both singular and plural. This practice originally arose out of legislation intended to ensure that the banknotes were uncluttered with a string of plurals. Because the "s"-less plurals had become "enshrined" in EU legislation, the Commission decided to retain those plurals in English in legislation even while allowing regular plurals in other languages. The Directorate-General for Translation's "English Style Guide" (a handbook for authors and translators working for the European Commission) previously recommended the use of regular plurals where appropriate, but as of May 2019, states that no "s" should be used.
