Oh, of course -- I didn't recognize "wahda," as I don't know that much Arabic and only know "one" as "wahid."Yep, it's one and a half. I can't remember where I learned it, but it was probably a Keti dvd. It's almost always a Keti dvd or a private/workshop with Barbara Wolfkamp!
Coincidentally, I learned just last night that the "official" Arabic name for chiftetelli is "wahid wa nos" or one-and-a-half, but hardly anyone calls it that; people mostly just say "shifta."
