A literary technique or literary device may be used by works of literature in order to produce a specific effect on the reader.

Literary technique is distinguished from literary genre as military tactics are from military strategy. Thus, though David Copperfield employs satire at certain moments, it belongs to the genre of comic novel, not that of satire. By contrast, Bleak House employs satire so consistently as to belong to the genre of satirical novel.

In this way, use of a technique can lead to the development of a new genre, as was the case with one of the first modern novels, Pamela by Samuel Richardson, which by using the epistolary technique strengthened the tradition of the epistolary novel, a genre which had been practiced for some time already but without the same acclaim.
