Catachresis

Catachresis, originally meaning a semantic misuse or error, is also the name given to many different types of figures of speech in which a word or phrase is being applied in a way that significantly departs from conventional usage. Examples of the original meaning include using "militate" for "mitigate", "chronic" for "severe", "travesty" for "tragedy", "anachronism" for "anomaly", "alibi" for "excuse", etc. As a rhetorical figure, catachresis may signify an unexpected or implausible metaphor.

Use in literature
Catachresis is often used to convey extreme emotion or alienation. It is prominent in baroque literature and, more recently, in dadaist and surrealist literature.
Use in philosophy and criticism
In Jacques Derrida's ideas of deconstruction, catachresis refers to the original incompleteness that is a part of all systems of meaning. He proposes that metaphor and catachresis are tropes that ground philosophical discourse.
Postcolonial theorist Gayatri Spivak applies this word to "master words" that claim to represent a group, e.g., women or the proletariat, when there are no "true" examples of "woman" or "proletarian". In a similar way, words that are imposed upon people and are deemed improper thus denote a catachresis, a word with an arbitrary connection to its meaning.
