Catachresis

Catachresis (from Greek κατάχρησις, "abuse"), originally meaning a semantic misuse or error—e.g., using "militate" for "mitigate", "chronic" for "severe", "travesty" for "tragedy", "anachronism" for "anomaly", "alibi" for "excuse", etc.—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 (or traditional) usage.

Variant definitions
There are various characterizations of catachresis found in the literature.

Examples
Dead people in a graveyard being referred to as inhabitants is an example of catachresis.

Example from Alexander Pope's Peri Bathous, Or the Art of Sinking in Poetry: Masters of this [catachresis] will say,
 * Mow the beard,
 * Shave the grass,
 * Pin the plank,
 * Nail my sleeve.

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.

In Calvin Warren's Ontological Terror: Blackness, Nihilism, and Emancipation, catachresis refers to the ways Warren conceptualizes the figure of the black body as vessel or vehicle in which fantasy can be projected. Drawing primarily from the "Look a Negro" moment in Frantz Fanon's Black Skin, White Masks, Chapter 5: "The Fact of Blackness", Warren works from the notion that "the black body…provides form for a nothing that metaphysics works tirelessly to obliterate", in which "the black body as a vase provides form for the formlessness of nothingness. Catachresis creates a fantastic place for representation to situate the unrepresentable (i.e., blackness as nothingness).

In the 20th century, other philosophers embraced the view that metaphorical "category mistakes" or "sort-crossings" such as catachresis also have the potential of leading unsuspecting users into considerable obfuscation of thought within the realm of epistemology. Included among them is the Australian philosopher Colin Murray Turbayne. In his book The Myth of Metaphor, Turbayne argues that the use of metaphor is actually essential to any language system which claims to embody richness and depth of understanding. He also demonstrates, however, the dangers associated with literal interpretations of several metaphorical constructs which prevail in the modern scientific materialism of the Western world including: the mechanistic Cartesian and Newtonian depictions of the universe as little more than a "machine", and the concepts of "substance" and "substratum". He further argues that modern man has unknowingly fallen victim to such metaphors through the repeated utilization of literal interpretation and has therefore needlessly rejected alternative metaphorical formulations which may be more beneficial in nature.
