Protected Lexicon Information

Merriam-Webster and HarperCollins have required encryption of the OTCWL, SSWL, OSPD and CSW lexicons within Zyzzyva. In order to support this encryption, NASPA Zyzzyva has built-in deadlines, as follows:

  • When you claim a license for a protected lexicon, the license will remain in effect until the expiry date of your NASPA membership at that point in time. When you later renew your NASPA membership, you should update the license to extend the deadline. You can manage your license from the Tools --> Manage Licenses menu in the program.
  • Periodically, the program will require the ability to check-in with the NASPA server and activate the license. For general members, this check will take place every six months, with a six month grace period; for certified directors, the check is required annually, with a one-year grace period. If the check-in is not performed, the program will only allow the protected lexicons to be used for word judging, until such time as the check-in completes successfully.
  • Each license is valid for use on a limited number of devices. If you need to use NASPA Zyzzyva on more devices than you are currently allowed, please contact info@scrabbleplayers.org to discuss your situation.


Obtaining a license and activating the license with the check-in process require internet access. If you need to install the protected lexicons on a machine without internet access, please contact info@scrabbleplayers.org for information about off-line activation.
