A double entendre is a figure of speech or a particular way of wording that is devised to have a double meaning, one of which is typically obvious, and the other often conveys a message that would be too socially unacceptable, or offensive to state directly.

A pun, also rarely known as paronomasia, is a form of word play that exploits multiple meanings of a term, or of similar-sounding words, for an intended humorous or rhetorical effect. These ambiguities can arise from the intentional use of homophonic, homographic, metonymic, or figurative language. A pun differs from a malapropism in that a malapropism is an incorrect variation on a correct expression, while a pun involves expressions with multiple interpretations. Puns may be regarded as in-jokes or idiomatic constructions, especially as their usage and meaning are usually specific to a particular language or its culture.
