I'm trying to learn some Arabic, and came across the word "yes" as "aywa" (in the Egyptian dialect). Easy, I thought, I'll just think of the Spanish expression. It then hit me that I've never actually seen this expression in writing. Does anyone know how it's spelled? It means something like oh, wow, and I've heard it many, many times in Spain, with the second syllable drawn out - "ay waaaaa." I've even used it myself, many times, and was understood. Does anyone know the background of this expression? I'm also wondering if it has Arabic roots.
