The lack of books and therefore lack of reading leads to reduce vocabulary. I read somewhere the average of known words by an Arabic speaker was substantially lower than English speakers.

When I switch to speaking Arabic (poorly) I struggle to find words because my vocab level is so bad. Imagine for an every day person, not being able to effectively express themselves. It would lead to a ton of frustration, miscommunication and misunderstanding.

I really need to improve my Arabic!
