Evans Simon. A Grammar of Middle Welsh

The Dublin Institute for Advanced Studies, 1970. — 312 p.Middle Welsh is the language of Wales as found in the written documents of the 12th to 14th centuries. A very useful reference book for Middle Welsh. Of course it would be tedious to read this cover to cover (as would be the case with most academic grammars), but it's very handy to have a copy if you start studying the language. The saving grace was the section on verbs, which at least had well set up paradigm charts. Описательная грамматика средне-валлийского языка. Основана на более ранней работе автора на валлийском языке «Gramadeg Cymraeg Canol».
