I once was curious about possibly learning Arabic. I left more confused after my initial research than I went in.
What's a good Arabic dialect to learn such that you're as intelligible as possible?
Fus-ha Arabic (High Arabic) is intelligible as it is used in official communication, academia, news papers, documentaries, etc. But obviously it is not spoken day to day.
When I was studying it, we were told Syro-lebanese was the cleanest and most easily understandable, with Egyptian a distant second despite being quite peculiar due to widespread popularity of their media production.
