== Frequently Asked Questions about the Word List ==
 
  
; What are all these official word lists?
+
== OTCWL2 (OTCWL2.1) ==
: 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: [[OSPD]] for school play, [[OTCWL]] 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 letters, and their inflections. For longer words, please consult OTCWL, beginning with its 2014 edition.
 
; Why is ZEN not acceptable?
 
: Because none of our source lexica list it spelled without a capital Z.
 
; 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 to OSPD1; it is reentering the lexicon as of OTCWL2014, because it is listed in one of our new source lexica.
 
; Why is a particular word in [[OTCWL]] but not in [[OSPD]]?
 
: Although both OTCWL and OSPD are edited by both NASPA and Merriam-Webster, the publications are edited at different times 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 Zyzzyva]].
 
; When can I use the latest word lists with Quackle, Zarf, Elise, ...?
 
: We are not aware of any plans by the developers of other software to license the current word list.

The Official Tournament and Club Word List was the official word reference for SCRABBLE play in the United States and Canada from 1998 to 2018, when it was replaced by the NASPA Word List. It was edited by the NASPA Dictionary Committee.

OTCWL2016

The fourth edition of OTCWL went on sale initially just before the 2016 North American SCRABBLE Championship and is available to members at the NASPA Store. It is a minor update, correcting errata from the previous edition, and including over 1,000 new words all of nine or more letters.

It was edited by the Dictionary Committee under the chairmanship of John Chew.

The Advisory Board established September 1, 2016 as the effective date of this lexicon for NASPA club and tournament play.

OTCWL2014

The third edition of OTCWL was the official word reference from 2015–04–10 to 2016–08–31.

It went on sale initially at the 2014 National SCRABBLE Championship and was available to members at the NASPA Store. For the first time, it includes base words of 10–15 letters and their inflections, which were formerly listed in the Long List.

It was the first word reference created by NASPA, edited by the Dictionary Committee under the chairmanship of Jim Pate.

OTCWL2 (OTCWL2.1)

The second edition of OTCWL was the official word reference for words of up to nine letters and their inflections from 2006–03–01 to 2015–04–09. It was edited by Merriam-Webster based on research conducted by the NSA Dictionary Committee under the chairmanship of Jim Pate.
