Geoffrey Chaucer was an English poet and author, best known for his work, The Canterbury Tales. Born around 1343, he is often called the "Father of English literature" because he wrote in English at a time when most literature was in Latin or French. His stories, told by a group of pilgrims traveling to Canterbury, explore various themes and characters, showcasing the diversity of medieval society. Chaucer's writing style was innovative, blending humor, realism, and social commentary. His use of the iambic pentameter and rhymed verse helped shape the English language and poetry. Today, his works remain influential and are studied in schools around the world.
