The Scrabble dictionary contains over 100,000 words, as of April 2015. There are thousands of new words added to the new edition from the previous version, including a number of commonly used slang words.
The Official Scrabble Dictionary is published by Merriam-Webster. The company offers an online version and a book version of its product. The current version of the actually book is in its fifth edition and includes words like "bromance," "hashtag" and "mojito." It also includes variant spellings along with the standard brief definitions, and help for fast word validation. The North American Scrabble Players Association endorses the book for use on many fronts, such as school and personal use.
