Today's word

bowdlerize \BOHD-ler-ize\ - 1. to expurgate by omitting or modifying parts considered vulgar  2. to modify by abridging, simplifying, or distorting in style or content

I knew that this represented a modification, but I actually had in my mind that it meant the opposite of its first definition because, even though I knew how to spell both words, I still confused the beginning with bawdy. Glad I never used it that way!
