A pun is not a literary work, but a rhetorical device which consists in the use of words similar in form or sound, but in different senses, close to one another in order to create an unexpected effect on the listener or reader. That is, it is an ambiguous game of words with sounds similar or alike, but with different meanings and applications. Puns are one of the rhetorical resources most used in humorous and advertising speeches.
