"A pleonasm is the use of redundant words, often in established phrases or idioms.

"I tried to write something, but it's hard to beat this excellent excerpt by the comedian George Carlin from When Will Jesus Bring the Pork Chops — spot the pleonasms:

"'My fellow countrymen, I speak to you as coequals, knowing you are deserving of the honest truth. And let me warn you in advance, my subject matter concerns a serious crisis caused by an event in my past history...At that particular point in time, I found myself in a deep depression, making mental errors which seemed as though they might threaten my future plans. I am not over-exaggerating.

'I needed a new beginning, so I decided to pay a social visit to a personal friend with whom I share the same mutual objectives and who is one of the most unique individuals I have ever personally met. The end result was an un­expected surprise. When I reiterated again to her the fact that I needed a fresh start, she said I was exactly right; and, as an added plus, she came up with a fi­nal solution that was absolutely perfect.

'Based on her past experience, she felt we needed to join together in a com­mon bond for a combined total of twenty-four hours a day, in order to find some new initiatives. What a novel innovation! And, as an extra bonus, she presented me with the free gift of a tuna fish. Right away I noticed an immedi­ate positive improvement. And although my recovery is not totally complete, the sum total is I feel much better now knowing I am not uniquely alone.'” - Jono Hey
