Sanas Cormaic

Sanas Cormaic (or Sanas Chormaic, Irish for "Cormac's narrative"), also known as Cormac's Glossary, is an early Irish glossary containing etymologies and explanations of over 1,400 Irish words, many of which are difficult or outdated. The shortest and earliest version of the work is ascribed to Cormac mac Cuilennáin (d. 908), king-bishop of Munster. It is an encyclopedic dictionary containing simple synonymous explanations in Irish or Latin of Irish words. In some cases he attempts to give the etymology of the words and in others he concentrates on an encyclopedic entry. It is held to be the first linguistic dictionary in any of the non-classical languages of Europe. Numerous of its entries are still frequently cited in Irish and Celtic scholarship.
