SCRABBLE® Dictionary and Wordlist Resources

OSPD4 The fourth edition of the Official SCRABBLE® Player's Dictionary (OSPD) was published by Merriam-Webster in June of 2005.  The NSA's dictionary committee was instrumental in creating this book, assisting the lexicographers at Merriam-Webster by combing through four source dictionaries for new words that meet the criteria for inclusion in the next edition of the Official Tournament and Club Word List (OTCWL).  The new version of this list was published by Merriam-Webster in January of 2006 and is available only to NSA members.
