The simplest dialects are the closest to my Palestinian dialect, specifically Levantine dialects, similar to Jordanian, Syrian, Lebanese, and Iraqi. I can perceive Gulf Arabic additionally, similar to Saudi, Qatari, Kuwaiti, Emirati, and Bahraini.
I feel that essentially the most troublesome dialects are Maghrebi Arabic – Moroccan, Tunisian, and Algerian Arabic. This might be as a result of international languages which interfered in these dialects, similar to French and Italian.
