I can do the ayn fine. But there's so much going on here. A glottal stop, then a short a then an ayn (which is difficult after a vowel, even more difficult when there's no vowel after it), then from that super guttural sound you have to suddenly shift your tongue up to do a trilled r before the if. It's nuts.
Wow .. Is it like this?? Emmm I didn't imagine this way before.. By the way in spoken Arabic "I mean when we speak everyday" It's not that important to do the mouth movements carefully.. I mean for this word "A3rif" it could be "A3rf" That means you don't have to tighten both ends of your mouth to get out the sound "i" in "ri" very well. Directly from the raa to the faa "rf"
If you said a3rf it's same .. Don't worry so a lot about little things. Most of Arabs don't make the sounds so well and we have different dialects, more and more make us ask each other "what does that mean?" So we know new words.
Sometimes new words we know make us laugh because it has another meaning in our dialect, or it's just strange and looks funny ^^
