What style of writing is Geoffrey Chaucer famous for?

Geoffrey Chaucer is most famously associated with the frame-tale style of writing, particularly through his well-known work, "The Canterbury Tales." In this collection, Chaucer employs a narrative framework that allows multiple characters to tell their own individual stories while traveling together on a pilgrimage. This technique not only creates a rich tapestry of diverse voices and genres, but it also invites exploration of themes related to society, morality, and human behavior.

The frame-tale structure is significant because it serves to connect various tales thematically and narratively, highlighting the interactions and differences among the storytellers. This method was innovative for its time and has influenced many other works in literature by showcasing how disparate stories can be woven together within a singular framework that enhances their meaning.
