Literary genre

Literary genres are typically defined by formal, thematic, and stylistic conventions. Aristotle's Poetics (c. 335 BCE) laid the groundwork by distinguishing epic poetry, tragedy, and comedy based on mode of imitation, medium, and object.¹ Later, the Romans, especially Horace, added a prescriptive tone, and Renaissance critics like Philip Sidney codified genres into a hierarchy. In the 18th century, the novel emerged as a new form that defied traditional categories, prompting ongoing debates about its generic status.²

Modern genre theory, influenced by Russian formalism and structuralism, treats genres as dynamic systems rather than fixed boxes. Mikhail Bakhtin's concept of the chronotope—the intrinsic connection of time and space in literature—helped analyze how genres shape narrative possibilities. The rise of genre fiction (mystery, science fiction, romance, fantasy) in the 19th and 20th centuries created a commercial distinction from "literary" fiction, though many authors deliberately blur these lines, as in the works of Margaret Atwood or Kazuo Ishiguro.³

Libraries and publishers rely on genre classification for organization and marketing. The Dewey Decimal Classification and Library of Congress Subject Headings assign specific numbers and terms to genres, while the publishing industry uses genres to target readerships.⁴ Beyond the major genres, there are numerous niche and hybrid categories: cli-fi (climate fiction), solarpunk, grimdark fantasy, cozy mystery, and new weird. These subgenres often emerge from fan communities and online forums before gaining academic attention.

Genre boundaries are often porous and historically contingent. For instance, the epistolary novel was a dominant form in the 18th century but is now rare, while creative nonfiction only gained recognition as a genre in the late 20th century. Some genres are defined by audience rather than form, such as young adult literature, which spans multiple genres. Genre also intersects with identity politics: the term Afrofuturism combines science fiction with African diaspora themes, and magical realism is often tied to Latin American literature but appears globally.⁵ The concept of "genre" itself has been critiqued as a tool of canon formation, marginalizing works that defy easy categorization.
