The dialect has existed for centuries and is distinct from what became
standard British English. The works of the 14th century poets, including
Sir Gawain and the Green Knight, the religious poem
St. Erkenwald, and other works of the
Gawain poet, are written in this dialect. Cheshire author
Alan Garner states "Of course [the Cheshire dialect] has changed, as all living language changes, since the time of the
Gawain poet. But when I read sections of the poem aloud to my father, he knew, and used, more than 90% of the vocabulary; and the phonetics of the vowels have scarcely changed." Early references include English proverbs and dialect words collected by
John Ray in the 17th century, and a glossary of Cheshire words compiled by
Roger Wilbraham in 1817 and expanded in 1826. These sources were expanded by
Egerton Leigh in a glossary published posthumously in 1877, which was an attempt to preserve a way of speech that was already under threat from "emigration, railways, and the blending of shires." Leigh notes that some words collected by Ray had already disappeared. Later reference works include Thomas Darlington's
Folk-speech of South Cheshire (1887) and Peter Wright's
The Cheshire Chatter (1979). ==Characteristics and usage==
