Question: What Irish word for the name of an island and a sovereign state is featured on Irish euro coins?

full_context: Document 1: United Ireland: United Ireland is the proposition that the whole of Ireland should be a single sovereign state. At present, the island is divided politically; the sovereign state of Ireland has jurisdiction over the majority of Ireland, while Northern Ireland is part of the United Kingdom. Achieving a united Ireland is a central tenet of Irish nationalism, particularly of both mainstream and dissident Irish republican political and paramilitary organisations. Unionists support Northern Ireland remaining part of the United Kingdom, and therefore oppose Irish unification.
Document 2: Coins of the Republic of Ireland: There have been three sets of coins in Ireland. In all three, the coin showed a Celtic harp on the obverse. The pre-decimal coins of the Irish pound had realistic animals on the reverse; the decimal coins retained some of these but featured ornamental birds on the lower denominations; and the euro coins used the common design of the euro currencies. The pre-decimal and original decimal coins were of the same dimensions as the same-denomination British coins, as the Irish pound was in currency union with the British pound sterling. British coins were widely accepted in Ireland, and conversely to a lesser extent. In 1979 Ireland joined the Exchange Rate Mechanism and the "punt" left parity with sterling; coin designs introduced after this differed between the two countries.
Document 3: Irish Traditional Music Archive: The Irish Traditional Music Archive – Taisce Cheol Dúchais Éireann is a national public archive, information centre, and resource centre intended to be of use to everyone with an interest in the contemporary art forms of Irish traditional song, instrumental music, and dance, and in their history. The Archive’s area of interest covers the performance traditions of the island of Ireland and the Irish diaspora – Irish-Britain, Irish-America, Irish-Australia, etc. – and those of all other performers of Irish traditional music throughout the world. In its attitude to the Irish and connected traditions, the Archive defines ‘traditional music’ in a broad and inclusive way.
Document 4: Penny (Irish decimal coin): The decimal one penny (1p) (Irish: "pingin" ) coin was the second smallest denomination of the Irish pound. It was first issued when the Irish currency was decimalised on Decimal Day, 15 February 1971. It was the second of three new designs introduced all in bronze, the others being a half-penny and a two pence coin. All featured ornamental birds designed by Irish artist Gabriel Hayes on the reverse.
Document 5: Home Nations: The Home Nations, or Home Countries, refers collectively to England, Scotland, Wales, and Northern Ireland (countries of the United Kingdom), and in certain sports (e.g. Rugby football) contexts, to England, Scotland, Wales and the whole island of Ireland. The term "Home Nations" is used in this second sense partly because Northern Ireland and the Republic of Ireland have a unified association structure in certain sports, such as the Irish Rugby Football Union. Formerly the phrase was applied in general in this same wider sense, such as the period between 1800 and 1922, before the political partition of Ireland, when the whole island was part of the United Kingdom. The term "Home Countries" (not to be confused with the "home counties") is also sometimes used, and is synonymous.
Document 6: Irish people: The Irish people (Irish: "Muintir na hÉireann" or "Na hÉireannaigh") are a Celtic nation and ethnic group native to the island of Ireland, who share a common Irish ancestry, identity and culture. Ireland has been inhabited for about 9,000 years according to archaeological studies (see Prehistoric Ireland). For most of Ireland's recorded history, the Irish have been primarily a Gaelic people (see Gaelic Ireland). Anglo-Normans conquered parts of Ireland in the 12th century, while England's 16th/17th century (re)conquest and colonization of Ireland brought a large number of English and Lowland Scots to parts of the island, especially the north. Today, Ireland is made up of the Republic of Ireland (an independent state), and the smaller Northern Ireland (a part of the United Kingdom). The people of Northern Ireland hold various national identities; including Irish, Northern Irish, British, or some combination thereof.
Document 7: Republic of Ireland: Ireland ( ; Irish: "Éire" ] ), also known as the Republic of Ireland ("Poblacht na hÉireann "), is a sovereign state in north-western Europe occupying 26 of 32 counties of the island of Ireland. The capital and largest city is Dublin, which is located on the eastern part of the island, and whose metropolitan area is home to around a third of the country's 4.75 million inhabitants. The state shares its only land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint George's Channel to the south-east, and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the "Oireachtas ", consists of a lower house, "Dáil Éireann ", an upper house, "Seanad Éireann ", and an elected President ("Uachtarán ") who serves as the largely ceremonial head of state, but with some important powers and duties. The head of government is the "Taoiseach " (Prime Minister, literally 'Chief', a title not used in English), who is elected by the Dáil and appointed by the President; the Taoiseach in turn appoints other government ministers.
Document 8: Portuguese euro coins: Portuguese euro coins show three different designs for each of the three series of coins. However, they are quite similar in that all contain old Portuguese royal mints and seals within a circle of seven castles and five escutcheons with silver bezants (all similar to what can be seen in the coat of arms and flag of Portugal) and the word "Portugal". Also featured in the designs, all done by Vítor Manuel Fernandes dos Santos, are the 12 stars of the EU and the year of minting.
Document 9: United Kingdom: The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) and colloquially Great Britain (GB) or simply Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, the United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland and many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of 242500 km2 , the United Kingdom is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth-most densely populated country in the European Union (EU).
Document 10: Éire: Éire (] ) is Irish for "Ireland", the name of an island and a sovereign state. The English pronunciation is ( ).
Document 11: Government of Ireland: The Government of Ireland (Irish: "Rialtas na hÉireann" ) is the cabinet that exercises executive authority in the Republic of Ireland.
Document 12: Five pence (Irish coin): The five pence (5p) (Irish: "cúig phingin" ) coin was a subdivision of the Irish pound. It was introduced in Ireland on Decimal Day, 15 February 1971 and reused the design on the shilling coin produced for the Irish Free State in 1928. Some shilling coins remained in circulation until the early 1990s, with the same nominal value as the five pence coin.
Document 13: Irish euro coins: Irish euro coins all share the same design by Jarlath Hayes, that of the harp, a traditional symbol for Ireland since the Middle Ages, based on that of the Brian Boru harp, housed in Trinity College, Dublin. The same harp is used as on the official seals of the Taoiseach, and government ministers and the Seal of the Uachtarán. The coins' design also features the 12 stars of the EU, the year of issue and the Irish name for Ireland, "Éire", in a traditional Gaelic script.
Document 14: Coat of arms of Ireland: The coat of arms of Ireland is blazoned as "Azure a harp Or, stringed Argent" (a gold harp with silver strings on a blue background). These arms have long been Ireland's heraldic emblem. References to them as being the arms of the king of Ireland can be found as early as the 13th century. These arms were adopted by Henry VIII of England when he ended the period of Lordship of Ireland and declared Ireland to be a kingdom again in 1541. When the crowns of England, Scotland and Ireland were united in 1603, they were integrated into the unified royal coat of arms of kingdoms of England, Scotland and Ireland. The harp was adopted as the emblem of the Irish Free State when it separated from the United Kingdom in 1922. They were registered as the arms of Ireland with the Chief Herald of Ireland on 9 November 1945.
Document 15: Irish Sign Language: Irish Sign Language (ISL, Irish: "Teanga Chomharthaíochta na hÉireann" ) is the sign language of Ireland, used primarily in the Republic of Ireland. It is also used in Northern Ireland, though British Sign Language (BSL) is also used there. Irish Sign Language is more closely related to French Sign Language (LSF) than to British Sign Language, though it has influence from both languages. It has influenced sign languages in Australia and South Africa, and has little relation to either spoken Irish or English.
