"In english for example you have : Book, Author, Library In Arabic (kitaab, kaatib, maktaba) which is the same root (k,t,b)"

I see might not be difficult for me to learn it since I know Swahili (the most commonly spoken language in East Africa, which has Arab influence) since those words are pronounced respectively: Kitabu(book), Katibu(secretary), Maktaba(library).

Arab is not really complicated. Trust me, I'm accustomed to more troublesome dialects in Africa.
