Your software editor, Bryan Skinner, must have been so busy poring through his dictionaries that he didn't have time to notice that the subtitle of my game - Lingo - The computer game that makes fun of the English language - is a play on words.

But two can play at that game too. In my book (the Oxford English Dictionary) 'play' in this sense is defined as "a sportive use of words, so as to convey a double meaning, or produce a fantastic, or humourous effect by similarity of sound with different of meaning; a pun." Exactly.
