In that case, Aysun must be a parcel of grace and elegance sent directly from the heavens. Everything about it, from the splash of white on a sea of black to the natural flow of the letters, makes me tremble in its wake. What a bundle of godly charm! (I just noticed that this name seems to be declining in Turkey and Azerbaijan -- why is that? It deserves a fair bit of attention in the Western world... indeed, Turkish names are making quite the impression at the moment, and I think that's a lovely thing. I've never heard it before, but I would like to experience it in person.)
I'm correcting my last statement! It is pronounced as it looks, not ay-shun as I said before since there isn't the little curving mark coming off the 's' (I don't know what it's called). So it's just how it looks. Ay-sun/ay-soon.
