Literal and figurative language

Literal and figurative language is a distinction within some fields of language analysis, in particular stylistics, rhetoric, and semantics. 
Literal usage confers meaning to words, in the sense of the meaning they have by themselves, outside any figure of speech. It maintains a consistent meaning regardless of the context, with "the intended meaning corresponding exactly to the meaning" of the individual words. Figurative use of language is the use of words or phrases that "implies a non-literal meaning which does make sense or that could [also] be true".
Aristotle and later the Roman Quintilian were among the early analysts of rhetoric who expounded on the differences between literal and figurative language.
In 1769, Frances Brooke's novel "The History of Emily Montague" was used in the earliest "Oxford English Dictionary" citation for the figurative sense of "literally"; the sentence from the novel used was, "He is a fortunate man to be introduced to such a party of fine women at his arrival; it is literally "to feed among the lilies"." This citation was also used in the OED's 2011 revision.
Within literary analysis, such terms are still used; but within the fields of cognition and linguistics, the basis for identifying such a distinction is no longer used.
Figurative language in literary analysis.
Figurative language can take multiple forms, such as simile or metaphor. "Merriam-Webster's Encyclopedia Of Literature" says that figurative language can be classified in five categories: resemblance or relationship, emphasis or understatement, figures of sound, verbal games, and errors.
A simile is a comparison of two things, indicated by some connective, usually "like", "as", "than", or a verb such as "resembles" to show how they are similar.
A metaphor is a figure of speech in which two "essentially unlike things" are shown to have a type of resemblance or create a new image. The similarities between the objects being compared may be implied rather than directly stated. The literary critic and rhetorician, I. A. Richards, divides a metaphor into two parts: the vehicle and the tenor.
An extended metaphor is a metaphor that is continued over multiple sentences.
Onomatopoeia is a word designed to be an imitation of a sound.
Personification is the attribution of a personal nature or character to inanimate objects or abstract notions, especially as a rhetorical figure.
An oxymoron is a figure of speech in which a pair of opposite or contradictory terms is used together for emphasis.
A paradox is a statement or proposition which is self-contradictory, unreasonable, or illogical.
Hyperbole is a figure of speech which uses an extravagant or exaggerated statement to express strong feelings.
Allusion is a reference to a famous character or event.
An idiom is an expression that has a figurative meaning unrelated to the literal meaning of the phrase.
A pun is an expression intended for a humorous or rhetorical effect by exploiting different meanings of words.
Standard pragmatic model of comprehension.
Prior to the 1980s, the "standard pragmatic" model of comprehension was widely believed. In that model, it was thought the recipient would first attempt to comprehend the meaning as if literal, but when an appropriate literal inference could not be made, the recipient would shift to look for a figurative interpretation that would allow comprehension. Since then, research has cast doubt on the model. In tests, figurative language was found to be comprehended at the same speed as literal language; and so the premise that the recipient was first attempting to process a literal meaning and discarding it before attempting to process a figurative meaning appears to be false.
Reddy and contemporary views.
Beginning with the work of Michael Reddy in his 1979 work "The Conduit Metaphor", many linguists now reject that there is a valid way to distinguish between a "literal" and "figurative" mode of language.
