A literary trope is the use of figurative language – via word, phrase, or even an image – for artistic effect such as using a figure of speech. The word trope has also come to be used for describing commonly recurring literary and rhetorical devices,motifs or clichés in creative works. The term trope derives from the Greek τρόπος (tropos), "turn, direction, way", derived from the verb τρέπειν (trepein), "to turn, to direct, to alter, to change". Tropes and their classification were an important field in classical rhetoric, and was taken up again in modern criticism, especially deconstruction. Tropological criticism (not to be confused with Tropological reading, a type of biblical exegesis) is the historical study of tropes, which aims to "define the dominant tropes of an epoch" and to "find those tropes in literary and non-literary texts", an interdisciplinary investigation of whom Michel Foucault was an "important exemplar".
Rhetoricians have closely analyzed the great variety of "turns and twists" used in poetry and literature and have provided an extensive list of precise labels for these poetic devices. Examples include:
Allegory – A sustained metaphor continued through whole sentences or even through a whole discourse. For example: "The ship of state has sailed through rougher storms than the tempest of these lobbyists."
Antanaclasis – is the stylistic trope of repeating a single word, but with a different meaning each time. Antanaclasis is a common type of pun, and like other kinds of pun, it is often found in slogans.
Irony – creating a trope through implying the opposite of the standard meaning, such as describing a bad situation as "good times".
Metaphor – an explanation of an object or idea through juxtaposition of disparate things with a similar characteristic, such as describing a courageous person as having a "heart of a lion".
Metonymy – a trope through proximity or correspondence. For example, referring to actions of the U.S. President as "actions of the White House".
Synecdoche – related to metonymy and metaphor, creates a play on words by referring to something with a related concept: for example, referring to the whole with the name of a part, such as "hired hands" for workers; a part with the name of the whole, such as "the law" for police officers; the general with the specific, such as "bread" for food; the specific with the general, such as "cat" for a lion; or an object with the material it is made from, such as "bricks and mortar" for a building.
