I would add Syrian to that list.

But even within these dialects, there are regional dialects that might be difficult to understand even for native speakers from that same country.

For example, Tunisian Arabic can (roughly) be divided into northern and southern dialects. I've met people in the north who think I'm from Libya because of some words that are shared with southern Tunisian Arabic. Tunisia is a relatively small country, so imagine the variation in dialects in Egypt!

If you're interested in learning Arabic, don't let this scare you! The "generic" Egyptian, Lebanese, and Syrian dialects will easily be understood by most Middle Easterners and a fair chunk of North Africans.

But note that Egyptian Arabic is very different from Lebanese and Syrian Arabic (which both are in the Levantine Arabic family).

Definitely! I was just pointing out that these three dialects are the most universally understood, primarily due to their domination of Arabic music and film/TV.
