That's How It Happened

These 200 words were all removed from the Official Scrabble Players Dictionary in 1993, despite appearing in the equivalent Merriam-Webster. I've been playing online Scrabble a whole lot in the last fortnight, and I'm starting to get very confused depending on whether I'm using UK (OSW), US (OSPD) or international (SOWPODS), word lists. For future reference, if you are playing chez moi, house rules dictate that all of the following are not only allowable, but actually encouraged for light relief:
