Geoffrey Chaucer, often hailed as the 'Father of English Literature,' was one of the most groundbreaking figures of the Middle Ages. Born around 1343, Chaucer became an unparalleled force in literature, making significant contributions that remain influential to date. His seminal work, 'Canterbury Tales,' is a collection of over 20 stories told by a group of pilgrims travelling to Canterbury. In a bold and revolutionary move, Chaucer chose to write this work in Middle English, a language spoken by the common people, at a time when Latin and French were the dominant languages of literature. This decision not only gave voice to ordinary citizens but also showcased the beauty and versatility of the English language. In his tales, Chaucer painted a vivid picture of 14th-century English society, delving into various aspects of life. His stories offered incisive commentary on societal norms, critiqued religious practices, and explored the depths of human nature. The tales, filled with humor, irony, and wisdom, provide us with a comprehensive understanding of the era's culture and mindset. Chaucer's daring use of vernacular English broke from tradition and reshaped the literary landscape. His influence extended beyond his lifetime, laying the groundwork for future English writers and sparking a shift towards using English in literature. Today, his invaluable contributions continue to resonate in the realm of literature, affirming his place as a true pioneer.
