My biggest problem letter is mim. It essentially disappears in a lot of styles. If I was more fluent I’m sure I’d recognize the words more readily and know when to look for it. I don’t find the rest of the letters too difficult even at my basic level.
I was struck by the lack of books in the homes of even educated people in Yemen. I once went to a book fair in Sana’a that was well attended. Think it was on a college campus. I don’t remember seeing many novels in Arabic, they were mostly in English and French. I had been told that if someone sent me any books in the mail they would have to be cleared by the censor before I would get them. That pretty much equated to never getting them. The book fair was a relief. I picked up David Copperfield and Women in Love and that was enough to last me until I made a trip out of the country.
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!
