Hello
I saw in web site that the old name of Ankara
was A(n)kuwash from hittite
but i don't what it means
Hittite Ankuwash < Celtic Ancyra < Now Ankara

It's easy to connect A(n)kuwash with Grec Ankyra (Hook/Anchor
<Anchoring/Harbor) but Ankara is very far from the black sea and i
didn't found big rivers to bring boats to this city

Does anybody knows what does it means "A(n)kuwash" ?
Does Celtic(Galatian) Name Ancyra come from Grec Ankyra ?
Does any possibility to connect A(n)kuwash with IE Ang/Ank- = Narrow ?

thanks
