The distinction between literal and figurative language exists in all natural languages; the phenomenon is studied within certain areas of language analysis, in particular stylistics, rhetoric, and semantics.
Literal language is the usage of words exactly according to their direct, straightforward, or conventionally accepted meanings: their denotation.
Figurative (or non-literal) language is the usage of words in addition to, or deviating beyond, their conventionally accepted definitions[1][2] in order to convey a more complex meaning or achieve a heightened effect.[3] This is done by language-users presenting words in such a way that their audience equates, compares, or associates the words with normally unrelated meanings. A common intended effect of figurative language is to elicit audience responses that are especially emotional (like excitement, shock, laughter, etc.), aesthetic, or intellectual.
The ancient Greek philosopher Aristotle, and later the Roman rhetorician Quintilian, were among the early documented language analysts who expounded on the differences between literal and figurative language.[4] A comprehensive scholarly examination of metaphor in antiquity, and the way its use was fostered by Homer's epic poems The Iliad and The Odyssey, is provided by William Bedell Stanford.[5]
Within literary analysis, the terms "literal" and "figurative" are still used; but within the fields of cognition and linguistics, the basis for identifying such a distinction is no longer used.[6]
^"Figure of speech." Merriam-Webster Dictionary.

ISBN978-0080965000. Retrieved 23 December 2012. Traditional scholars maintain a strict dichotomy between figurative language and ordinary or literal language. This conventional aesthetic sense of figurative language no longer reflects current usage. Today, the term 'metaphor' has replace 'figurative language' with the special sense of a cognitive device used to explain how people categorize reality and store abstractions of that physical existence in their brain. [...] The essence of the literal-figurative debate revolves around whether or not metaphor is a deviation from some pristine ordinary language or whether it is a basic form of linguistic expression.
