what is it called when a saying has two meanings
Double entendre A double entendre (/ˌdʌbəl ɒnˈtɒndrə/; French pronunciation: ​[dubl ɑ̃.tɑ̃dʁ(ə)]) is a figure of speech or a particular way of wording that is devised to be understood in two ways, having a double meaning. Typically one of the meanings is obvious, given the context whereas the other may require more thought. The innuendo may convey a message that would be socially awkward, sexually suggestive, or offensive to state directly (the Oxford English Dictionary describes a double entendre as being used to "convey an indelicate meaning", whilst Longman Dictionary of Contemporary English defines it as "a word or phrase that may be understood in two different ways, one of which is often sexual").[1]
