Containing around 3,700 dialect words from both Cornish and English,, this glossary was published in 1882 by Frederick W. P. Jago (1817–92) in an effort to describe and preserve the dialect as it too declined and it is an invaluable record of a disappearing dialect and way of life.
The DAG is the first onomasiological dictionary of Old Gascon. It covers the period from the earliest extant documents to the 17th century, taking into account all relevant idioms and sources (incl. medieval Latin and regional French). From fascicle 12 onwards the dictionary is published with a new, clearer article structure that provides more scope for semantic description and the presentation of idioms and contexts.
