Calembour is a noun that refers to a play on words. 

The origin of our word of the day is unknown, but you could think of it as a synonym of pun. Here’s an example of calembour in use:

I was hoping I could break the ice at the job interview with a calembour or two. I mean, who doesn’t like a good pun every now and then. Apparently, the guy interviewing me didn’t like them. My pun-manship didn’t get a single snicker out of him.
