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.
In word formation, the French suffixes -ment and -age have similar meanings (e.g. gonflement - swelling, gonflage - inflating). This book analyses the abstract meaning of the two suffixes and shows their systematic differences at an abstract semantic level. As its starting point it considers the speaker's knowledge and the criteria by which these suffixes are used to form derivations.
