Place names in Ireland
The vast majority of placenames in Ireland are anglicisations of Irish language names; that is, adaptations of the Irish names to English phonology and spelling. However, some names come directly from the English language, and a handful come from Old Norse and Scots. The study of placenames in Ireland unveils features of the country's history and geography and the development of the Irish language. The name of Ireland itself comes from the Irish name Éire, added to the Germanic word land. In mythology, Éire was an Irish goddess of the land and of sovereignty.
In some cases, the official English or anglicised name is wholly different from the official Irish language name. An example is Dublin: its name is derived from the Irish dubh linn, but its Irish name is Baile Átha Cliath.
Etymology
Names of Irish Gaelic origin
For most of the Gaelic period, there were very few towns or large settlements in Ireland. Hence, most places were named after noteworthy features of the landscape, such as hills, rocks, valleys, lakes, islands, and harbours. As time went on, more places were named after man-made features, such as churches, castles, and bridges. Some of the most common elements found in Irish placenames are shown in the table below.
