It is worth mentioning that Middle English consisted of dialects that significantly differed from one another. Chaucer’s English is similar enough to modern English that bookish people today can quickly get used to it with the help of an annotated edition of the Canterbury Tales. But Sir Gawain and the Green Knight or the less popularly known writers of the Middle English period like the Pearl-poet or William Langland are more challenging and generally only ventured by specialists, and everyone else relies on translations.
