Meanings of Irish place names

Many of the place names in Ireland are anglicised versions of the way the original Irish (Gaelic) name was spoken. The settlers tried to preserve the place names by writing them phonetically in English. Although this resulted in some beautiful sounding place names, it lost the meaning behind them.

This list is not exhaustive, but gives examples of the more common elements of Irish place names.
