The St. Louis Post-Dispatch used the non-word sillily on the front page of its sports section last week.  It reminds me of the Parisian bus with the “slididing” top and the “screeninings” available at the Lions Club.  I think slididing and screeninings were probably typos, but I have a hunch this sportswriter thought he needed to change the adjective silly (the kind of hair extensions) to an adverb, even though it does not function as an adverb (how, where, when).  He changed the y to i and added -ly.  Well, at least he knows how to form adverbs, even if he doesn’t know how to use them.  Aaarrgghh!
