The updated international wordlist (aka Collins™ or CSW19) is now available, and we at WPGO are excited to start using the newly added words like EW, OK, and ZE. To match other organizations around the globe, WGPO will start using CSW19 at all WGPO tournaments and clubs using the international lexicon effective July 1st, 2019. This means that CSW19 will be used for the Collins™ division at Word Cup 2019 in Coral Gables, FL. Of course, this update will have no effect for the majority of our players that solely use the North American lexicon (TWL).
Freely downloadable copies of programs using CSW19, including Collins Zyzzyva, are available at
Happy studying to all, and see you with the new words in Coral Gables!
