First dictionary of ancient Celtic spoken 2,000 years ago to be compiled by linguists

Inscriptions on stones using the Ogham alphabet will provide source material for the new Celtic dictionary. 

It is not likely to be a hefty volume because the vast majority of the material has been lost in the mists of time. 

But the remnants of a language spoken in parts of the UK and Ireland 2,000 years ago are being collected for what is being billed as the first complete dictionary of ancient Celtic.
