Double entendres and puns!?

Question

What is the difference between a double entendre and a pun??

Answer 1

A double entendre has two entirely different meanings, intentional or otherwise. A pun is a play on words only intended to have one non-literal meaning, usually based on the sound of the word or phrase.

Edit: Examples

Double entendre: "Steve Ryder covering the US Masters: 'Ballesteros felt much better today after a 69.'" The report is referring to his score, but it obviously can mean something else.

Pun: "You can lead a horticulture, but you can't make her think."

Answer 2

Wikipedia has a very good explanation of the difference

Answer 3

A pun is a play on words.  A double entendre means double meaning.
