If you"re using the 1991 edition or the 1978 original, you"re woefully behind the Scrabble-playing times. With more than 100,000 2- to 8-letter words, there are some interesting additions ("aargh," "aarrgh," and "aarrghh" are all legitimate now), while words they consider offensive are no longer kosher. Why subscribe to the Scrabble dictionary"s changeable lexicon? Well, it ends the argument of whose dictionary to use, but the main reason is that it"s the winner"s dictionary, and why play Scrabble if not to win? Memorize those 2- and 3-letter words, and your Scrabble game becomes lethal.
