I subscribed to a word-of-the-day thing about 10 years ago. One of the words was a noun for the instance of describing something redundantly. Every now and then I hear someone do this and die not being able to remember the word for it. As luck would have it, I can't muster an example I feel very confident about but perhaps "it was too overdone" where "it was overdone" would suffice would suffice as an example...
