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.
This monograph grew out of a project funded by the Berkeley-Stanford Joint Centers vocabularies project. It covers a wide range of linguistic aspects of the Gikuyu language, most of which do not exist in existing grammars of the language. Aspects covered include: consonantal mutations; syllabification; the gender class system; types of nominalizations; the noun phrase; the verb phrase; possessor ascension; the tense aspect paradigms. Additionally, the monograph includes a short lexicon of cultural terminology relating to aspects of Gikuyu life such as the rights of passage; garments and ornaments; foods; the environment; etc.
