what is a pun?
The pun, also called paronomasia, is a form of word play that suggests two or more meanings, by exploiting multiple meanings of words, or of similar-sounding words, for an intended humorous or rhetorical effect. recursive pun is one in which the second aspect of a pun relies on the understanding of an element in the first. For example, the statement  Ï is only half a pie. (Ï radians is 180 degrees, or half a circle, and a pie is a complete circle).
