Likely we all remember Geoffrey Chaucer’s The Canterbury Tales. It was written in the late 1300’s in Middle English. Here are the first few lines:
Whan that Aprille with his shoures soote
The droghte of Marche hath perced to the roote,   Â
And bathed every veyne in swich licour,       Â
Of which vertu engendred is the flour;Â Â Â Â Â Â Â Â Â Â
Whan Zephirus eek with his swete breeth
Inspired hath in every holt and heeth
The tendre croppes, and the yonge sonne
I am sure we are all flashing back to high school and suffering though this classic long work. Most of us read an updated version written in modern English, thankfully. Likely you remember the discussion of the evolution of language.
