The Irish language is of Celtic origin and dates back to their invasion. Today the language is still alive and with it the old sayings, songs, stories and customs. Even Gaelic place names that we take for granted can be very significant in terms of folklore. If we look at some place names in Kerry, for example Ballaghisheen which is derived from the Gaelic Ballagh Oisin, meaning the mountain pass of Oisin, a major figure in Irish folklore. Similarly, Da Chich Anand in Rathmore are named after Anu, the great goddess mother of the Tuatha De Danaan.
Language is a powerful link with the past.
The story of Tir na nOg told in Gaelic today would be reasonably similar in content and language to the story heard by children in the Celtic era. The survival of Irish folklore is largely dependent on the people. Certainly the fact that Ireland has such an extensive history is important, as is the native language and surviving customs and traditions. Ireland in the 21 st century has seen a marvelous revival of the Irish language , Irish music , dance and national pride. This pride also extends to an excellent economic performance and achievements in sport.
