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 book is concerned with frame theory, which in recent years has experienced an immense growth in interest, not only in Germanic Linguistics. Frames are knowledge structures in the long-term memory which are of relevance for understanding expressions in language. Thus, for example, the gratuity frame makes knowledge available about eating in a restaurant. Frames can also be deployed as analytical tools. This is demonstrated using the metaphor of "financial investors as locusts" coined by the then-SPD Minister of Labour Franz Müntefering.
