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 mixed metaphor is a succession of incongruous or ludicrous comparisons. Also known (playfully) as a mixaphor. Although many style guides condemn the use of mixed metaphors, in practice most of the objectionable combinations (as in the examples below) are actually clichÃ©s or dead metaphors. See Examples and Observations below.
