I find Mandarin Chinese to be much easier to handle than Arabic. At least for the spoken language. The pictographs are a huge learning curve by themselves, but actually independent of the spoken language. The written form is understood by Mandarin and Cantonese speakers, yet their spoken language is vastly different.
Sounds like you speak several languages. I’ve never been able to learn anything but English, which has always sort of bothered me.
The whole lack of vowels as well as the right-to-left writing is also found in Hebrew as well.
And it is a real pain in the butt for newcomers to learn without vowels. Which is why I gave it up and learned Korean.
Which has it’s own problems (like frequently dropping the subject in sentences, so you don’t know who their talking/writing about).
