Definition. An extended metaphor is a comparison between two unlike things that continues throughout a series of sentences in a paragraph or lines in a poem. Also known as a conceit or a megametaphor. Extended metaphor is a common literary device, particularly in poetry.
A metaphor is a figure of speech that refers, for rhetorical effect, to one thing by mentioning another thing. It may provide clarity or identify hidden similarities between two ideas. Antithesis, hyperbole, metonymy and simile are all types of metaphor.
