Science fictionScience fiction (sometimes shortened to SF or sci-fi) is a genre of speculative fiction, which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, and extraterrestrial life. Science fiction can trace its roots to ancient mythology. It is related to fantasy, horror, and superhero fiction and contains many subgenres. Its exact definition has long been disputed among authors, critics, scholars, and readers.
FictionFiction is any creative work, chiefly any narrative work, portraying individuals, events, or places that are imaginary, or in ways that are imaginary. Fictional portrayals are thus inconsistent with history, fact, or plausibility. In a traditional narrow sense, "fiction" refers to written narratives in prose often referring specifically to novels, novellas, and short stories. More broadly, however, fiction encompasses imaginary narratives expressed in any medium, including not just writings but also live theatrical performances, films, television programs, radio dramas, comics, role-playing games, and video games.
Speculative fictionSpeculative fiction is an umbrella category of fiction that, in its broadest sense, encompasses all the genres that depart from realism, or imitating ordinary reality, such as in the context of supernatural, futuristic, and other imaginative realms. This catch-all genre thus includes, but is not limited to, science fiction, fantasy, horror, superhero fiction, alternate history, utopian and dystopian fiction, and supernatural fiction, as well as combinations thereof (for example, science fantasy).
LiteratureLiterature is any collection of written work, but it is also used more narrowly for writings specifically considered to be an art form, especially prose fiction, drama, poetry, and including both print and digital writing. In recent centuries, the definition has expanded to include oral literature, also known as orature much of which has been transcribed. Literature is a method of recording, preserving, and transmitting knowledge and entertainment, and can also have a social, psychological, spiritual, or political role.
Genre fictionGenre fiction, also known as formula fiction or popular fiction, is a term used in the book-trade for fictional works written with the intent of fitting into a specific literary genre in order to appeal to readers and fans already familiar with that genre. A number of major literary figures have written genre fiction. John Banville publishes crime novels as Benjamin Black, and both Doris Lessing and Margaret Atwood have written science fiction.
