If you ever needed proof that remembering lists of words doesn't mean you can speak the language, here it is.
48-year-old New Zealander, Nigel Richards, is the French-language world Scrabble champion, but he can't speak French.
(He is 3 times world Scrabble champion, 5 times US champion, and has won 12 titles in the King’s Cup championship in Bangkok, but became world Champion of Francophone Scrabble, after memorizing all possible words in the official French scrabble dictionary, with two to 10 letters.
Throw those vocabulary lists away.)
