Ireland is the third largest island in Europe behind Great Britain and Iceland. Ireland lies to the northwest of Continental Europe and is surrounded by hundreds of islands. Politically, the Republic of Ireland covers five sixths of the island, with Northern Ireland, part of the United Kingdom, covering the remainder in the northeast. The name 'Ireland' derives from the Irish word Eire, with the addition of the Germanic word 'land'.
The population of the island is slightly under six million, with almost 4.25 million in the Republic of Ireland. Traditionally, Ireland is subdivided into four provinces: Connacht, Leinster, Munster and Ulster; and, in a system developed between the 13th and 17th centuries, 32 counties. Twenty-six of the counties are in the Republic of Ireland, and the remaining six (all in Ulster) are in Northern Ireland.

Irish (Gaeilge) is a Celtic language of the Goidelic branch spoken in Ireland. Although once spoken across the whole of the island, it is currently a minority vernacular in Ireland, spoken in specific communities and most particularly in officially-recognised Gaeltachtai, which exist around the Republic of Ireland. It is constitutionally upheld as the national and first official language of the Republic of Ireland, and it is an official language of the European Union. It is also an officially recognised minority language in Northern Ireland.
