Can you learn another language by playing Scrabble?
Frankly, I believe so. However, it takes a lot of patience with oneself and a decent bilingual dictionary. It helped me with my English. My primary language is Spanish. By the time I started kindergarten, I knew how to speak Spanish, French, and Italian. Until that point, I did not need to study English.
My parents felt that one of the most effective methods to improve my English skills would be to play Scrabble. It was challenging because I would try to spell terms in Spanish or French that the English dictionary would not take as valid English.
Within two years, my knowledge of the English language improved to the level of any of my previous classmates. I’m still playing Scrabble in Spanish, English, and French more than a half-century later. I assume you enjoy trying it. However, you should be aware that it might be a challenging effort.
