Bakhtin distinguishes between primary and secondary speech genres. Secondary, or complex, speech genres develop in highly organized cultural communication and are usually mediated (written) and removed from the context of "actual reality." Secondary genres, as "historical formations," tend to "absorb and digest" primary speech genres, "reaccentuating" the simpler genres (Bakhtin, 1986, p. 62).

Bakhtin (1986) gives as examples "novels, dramas, all kinds of scientific research, major genres of commentary, and so forth" (p. 62). Literary genres are one kind of secondary genre, but not the only kind.
