What is the hardest language to learn?

[Bloodst3r]

As some people said, Arabic is way too hard, my first language is Arabic, and I still find it hard to learn Arabic, Writing and specially talking is hard ( for non-Arabians ), that's apart from grammar, grammar is my biggest problem atm at learning Arabic.

Also there is a lot of Arabian countries that each uses a different accent, my Arabic accent is Egyptian, if I perfected Egyptian Arabic, still wont be counted that I am perfect in Arabic, until I learn each country accent and stuff    

I guess there is more than 5 accents or something, however good luck
