This 21-slide PowerPoint is intended for an AP British literature class or a college-level class. It requires that the teacher have some understanding of both Old and Middle English, so that the examples can be made clear to the students. It uses the Lord's Prayer as an example of how case and number were indicated through word ENDINGS. Then it uses the Prologue to the Canterbury Tales as an example of which word endings remained, but how ME tended to convey meaning through word order rather than word ending. Finally, it focuses on a particular meaningful word in the CT--the word "worthy"--and shows how Chaucer uses that word both literally and ironically in regard to various of the pilgrims.
