Dalkey is an affluent suburb of Dublin, and a seaside resort southeast of the city, and the town of Dún Laoghaire, in the county of Dún Laoghaire–Rathdown in the traditional County Dublin, Ireland. It was founded as a Viking settlement and became an active port during the Middle Ages. According to chronicler John Clyn (c.1286–c.1349), it was one of the ports through which the plague entered Ireland in the mid-14th century. In modern times, Dalkey has become a seaside suburb that attracts some tourist visitors.

Irish, also known as Irish Gaelic or simply Gaelic, is a Goidelic language of the Insular Celtic branch of the Celtic language group, which is a part of the Indo-European language family. Irish is indigenous to the island of Ireland and was the population's first language until the 19th century, when English gradually became dominant, particularly in the last decades of the century. Today, Irish is still commonly spoken as a first language in areas of Ireland collectively known as the Gaeltacht, in which only 2% of Ireland's population lived in 2022.
