Collins Scrabble Words

CollinsScrabbleWords (CSW, formerly SOWPODS) is the word list used in English-language tournament Scrabble in all countries except the US and Canada, although some Scrabble tournaments in the US and Canada are also organized with divisions that use CSW as their lexicon, some under the auspices of organizations such as the Collins Coalition. The term SOWPODS is an anagram of the two abbreviations OSPD (Official Scrabble Players Dictionary) and (Official Scrabble Words), these being the original official dictionaries used in various parts of the world at the time.

Currently the two main sources for the words making up the combined list (generally known as Collins or CSW) are:

• The British words. Derived from two sources; the Collins English Dictionary and the Collins Corpus, and
• The American words. From the NASPA Word List, formerly Official Tournament and Club Word List, or TWL, derived from the Merriam-Webster's Dictionary and four other collegiate dictionaries. Latest version is NWL2023.
