Where's the negation in 〇〇も書けなりました?


I'm not sure what this example sentence is trying to teach. The translation is
really throwing me off.

> 易しい漢字も書けなりました  
>  I cannot even write easy kanji anymore

I see the "even ... easy kanji" and the "anymore" in なりました, but where's the
cannot coming from?




This is a typo for 書け **なく** なりました (have become unable to write).

Where did the example sentence come from?

The / only operates on "なった" and not "なく なった": ![enter image description
