The NASPA list includes all of the words in the Official Scrabble Players Dictionary, the go-to source for living-room and app players in North America, plus a lot more.

Chew, thanks in part to his Scrabble work, was recently named editor of a planned dictionary of Canadian English. While Merriam-Webster and four other Scrabble source dictionaries explicitly state that the plural of roux is roux, the fourth edition of Webster’s New World College Dictionary, published in 1999, does not specify a plural. Steve Kleinedler, the managing editor of the fifth edition of Webster’s New World (2014), said NASPA’s interpretation is incorrect.
