 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 too 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").A double entendre may exploit puns or word play to convey the second meaning.
