metaphor

Etymology

From Middle French métaphore, from Latin metaphora, from Ancient Greek μεταφορά (metaphorá), from μεταφέρω (metaphérō, “I transfer, apply”), from μετά (metá, “with, across, after”) + φέρω (phérō, “I bear, carry”).

noun

1. (uncountable, rhetoric) The use of a word or phrase to refer to something other than its literal meaning, invoking an implicit similarity between the thing described and what is denoted by the word or phrase.
   Coordinate term: simile (when the similarity is made explicit by the words like or as)
   The next group of computational approaches to metaphor assume that metaphor is basically a hidden analogy. 2013, Eileen Cornell Way, Knowledge Representation and Metaphor, page 157
2. (countable, rhetoric) A word or phrase used in such implied comparison.
   A Metaphor may be changed into a Simile, and also into plain language, containing neither metaphor nor simile. Thus: Metaphor. — Idleness is the rust of the soul. Simile. — As rust is to iron, so is idleness to the soul, taking away its strength and power of resistance. Plain. — Idleness takes away from the soul its strength and power of resistance. 1874, John Seely Hart, First Lessons in Composition, page 92
   1979, Daniel Breazeale (translator), Friedrich Nietzsche, On Truth and Lies in a Nonmoral Sense [1873, Über Wahrheit und Lüge im außermoralischen Sinn], in Philosophy and Truth, page 84, quoted in 1998, Ian Markham, Truth and the Reality of God: An Essay in Natural Theology, page 103, What then is truth? A movable host of metaphors, metonymies, and anthropomorphisms: in short, a sum of human relations which have been poetically and rhetorically intensified, transferred, and embellished, and which, after long usage, seems to a people to be fixed, canonical, and binding. Truths are illusions which we have forgotten are illusions; they are metaphors that have become worn out and have been drained of sensuous force, coins which have lost their embossing and are now considered as metal and no longer as coins.
