This Glossary is designed as a companion to William Langland's dream vision poem, Piers Plowman, widely regarded as the greatest literary work in Middle English before Chaucer. It glosses and explains over 5000 English words, and foreign words used as if English, in the A, B and C texts of Piers Plowman printed in the critically-acclaimed Athlone editions. Where possible, it illustrates words with examples from all three versions.
