Academy of Sciences. The spelling is also in accordance with the word Európa ("Europe") in Hungarian. Hungarian language does not use plural after numerals, as numerals already express plural; however, both euró and cent can take suffixes regarding to grammatical cases, just as: Accusative case: eurót Dative case: eurónak Instrumental case: euróval ("with euro") Causative case: euróért ("for euro") etc. On introduction of the euro, Hungary—along with Lithuania, Latvia, and Slovenia—struggled for the euro to be written in its official documents according to its own usage and spelling, in contrast with Community law, which provides for a single name throughout the Union (in the nominative singular and taking account of different alphabets). The Treaty of Lisbon, signed in 2009, contains the following declaration from Hungary, Latvia and Malta: 58. Declaration by the Republic of Latvia, the Republic of Hungary and the Republic of Malta on the spelling of the name of the single currency in the Treaties Without prejudice to the unified spelling of the name of the single currency of the European Union referred to in the Treaties as displayed on the banknotes and on the coins, Latvia, Hungary and Malta declare that the spelling of the name of the single currency, including its derivatives as applied throughout the Latvian, Hungarian and Maltese text of the Treaties, has no effect on the existing rules of the Latvian, Hungarian or Maltese languages. Irish In Irish, the words euro and cent are used without change in spelling or pronunciation, and immune to the regular rules of Irish mutation after numbers; as such, they are ungendered, and the plural euronna is thus rarely encountered. The word ceint (plural ceinteanna ) has been in the lexicon since at least 1959 and is attested in printed literature, but is very rarely encountered. Linguist Michael Everson in a 2001 paper proposed a new masculine noun eoró (plural eorónna ), or alternatively eora (plural eoraí), derived from Eoraip ('Europe'), as being a more grammatically acceptable Irish term. However, it was not widely adopted and is not in common use. Irish also practices lenition after the numerals 2–6 (5 cheint) and eclipsis after numerals 7–10 (9 gceint, 8 n-eoró). However, as ceint is irregularly pronounced (no other Irish word has a soft c), lenition and eclipsis are usually not applied. Italian In Italian the word euro is used, as both singular and plural. Its standard pronunciation is
