Yalla (Let’s go)!
The friendly term yalla was one of three phrases I learned in Arabic when I visited Morocco a year and a half ago. For the first couple of days, I idly wondered why our guide kept saying “y’all” this and “y’all” that - until I stopped to ask him what he meant. How sheepish I felt to learn that he was encouraging us in the right direction and was not, in fact, poking fun at our American slang.
