Not only did Chaucer write in English but he wrote the of his characters?

Not only did Chaucer write in English, but he also wrote in the vernacular of his characters.

The vernacular refers to the language spoken by ordinary people in a particular region or time period. Chaucer used Middle English, the language spoken in England at the time, to create realistic and relatable characters.

This was a revolutionary move, as most literature at the time was written in Latin or French, languages that were understood by the elite but not by the common people.
