A double entendre is a figure of speech in which a spoken phrase is devised to be understood in either of two ways. Often the first (more obvious) meaning is straightforward, while the second meaning is less so: often risqué or ironic.
The Oxford English Dictionary defines a double entendre as especially being used to "convey an indelicate meaning." It may be used to express potentially offensive opinions without the risks of explicitly doing so.
A double entendre may exploit puns to convey the second meaning. Double entendres generally rely on multiple meanings of words, or different interpretations of the same primary meaning. They often exploit ambiguity and may be used to introduce it deliberately in a text. Sometimes a homophone (i.e. a different spelling that yields the same pronunciation) can be used as a pun as well as a "double entendre" of the subject.
Famous quotes containing the word double:
“On the death of a friend, we should consider that the fates through confidence have devolved on us the task of a double living, that we have henceforth to fulfill the promise of our friend’s life also, in our own, to the world.”
—Henry David Thoreau (1817–1862)
