'Geiriadur Cymraeg-Gwyddeleg' by Joe Mitchell (A Welsh-Irish dictionary)

This is the first Welsh-Irish dictionary to be published.  The volume includes over 12,500 headwords with examples of use, to promote a better understanding between speakers and writers of the two languages.  

The dictionary is an useful study aid particularly for those in the field of Celtic Studies, and ideal for those who are learning both the Welsh and Irish languages.
