Official Lexicon
LEXICON POLICY
Playing with the same Scrabble dictionary as the rest of the world is core to our mission. We are the Collins Coalition, after all. We value being citizens of the Scrabble-playing world and aspire to become a member of WESPA and to have CoCo tournaments rated by WESPA. To support those efforts and to encourage international players to come play their home lexicon on our home soil, we use the official WESPA lexicon at all CoCo tournaments and clubs.
2024 COLLINS LEXICON UPDATE
Effective Jan. 1, 2025, the official lexicon at all CoCo tournaments and clubs will be CSW24. This lexicon update was announced by WESPA in 2024 and adds 1,816 words to the Collins Scrabble dictionary. It removes three words deemed offensive, as well as their inflections.
