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:
“Actually being married seemed so crowded with unspoken rules and odd secrets and unfathomable responsibilities that it had no more occurred to her to imagine being married herself than it had to imagine driving a motorcycle or having a job. She had, however, thought about being a bride, which had more to do with being the center of attention and looking inexplicably, temporarily beautiful than it did with sharing a double bed with someone with hairy legs and a drawer full of boxer shorts.”
—Anna Quindlen (b. 1952)
