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:
“Even in harmonious families there is this double life: the group life, which is the one we can observe in our neighbour’s household, and, underneath, another—secret and passionate and intense—which is the real life that stamps the faces and gives character to the voices of our friends. Always in his mind each member of these social units is escaping, running away, trying to break the net which circumstances and his own affections have woven about him.”
—Willa Cather (1873–1947)
