Postmodern literature is a style of writing that emerged in the mid-20th century, characterized by its playful and experimental approach. It often blurs the lines between fiction and reality, using techniques like metafiction, where the text self-consciously refers to its own status as a work of art. Authors like Thomas Pynchon and Don DeLillo challenge traditional narratives, creating stories that can be fragmented or non-linear. Another key feature of postmodern literature is its focus on intertextuality, where texts reference or echo each other. This creates a rich tapestry of meaning, inviting readers to engage actively with the work. Themes of irony and parody are common, as writers explore the complexities of modern life and question established truths.
