<style class="text/css">dt { font-weight: bold}</style>== Frequently Asked Questions about the Word List == ; What are all these official word lists?: Any group of players can agree to use a particular word list or dictionary in their games. In officially sanctioned competitive play though, we all use one of a few official word lists designed for use with our game. Unlike regular dictionaries, for example, official word lists list all valid inflections for all listed words. Within NASPA's territory of the United States and Canada, the following word lists are officially recognized: The [[OSPDOTCWL1|first edition]] for school play, [[of OTCWL]] was the official word reference for regular competitive play, and [[CSW]] for international play.; Why is (my favorite word) not acceptable?: See [[How lexicons are compiled|how lexicons are compiled]].; Why is (a common nine-letter word) not in OSPD?: OSPD lists only words of up to eight nine letters, and their inflections. For longer words, please consult OTCWL, beginning with its 2014 edition.from 1998– Why is ZEN not acceptable?: Because none of our source lexica list it spelled without a capital Z.03– What's up with DA?: DA was deleted from the playing lexicon as of OSPD3 as a result of a major review of the original research that led 01 to OSPD12006– it is reentering the lexicon as of OTCWL2014, because it is listed in one of our new source lexica02–28.; Why is a particular word in [[OTCWL]] but not in It was edited by [[OSPD]]?: Although both OTCWL and OSPD are edited by both NASPA and Merriam-Webster, the publications are edited at different times ]] based on research conducted by different individuals according to different criteria. The commonest causes for a word appearing in OTCWL but not in OSPD are: being longer than 8 letters, being potentially offensive, being a possible trademark in some jurisdictions, having entered a source lexicon between the editorial deadlines for the two works, or differing editorial opinions concerning ambiguities in source lexica.; Can you send me a list of words that are in one lexicon but not in another?: For licensing and copyright reasons no, but you can probably make the list yourself using [[NASPA ZyzzyvaNSA]].; When can I use the latest word lists with Quackle, Zarf, Elise, ...?Dictionary Committee: We are not aware of any plans by under the developers chairmanship of other software to license the current word list.
