Thanks Lilit. Very good. I saw a similar pair with հագուստի-խանութ and others. Thanks again!

it is difficult to explain by Armenian grammar, I'll try to explain on examples. հագուստ = clothing when we want to say "part of the clothing" we say "հագուստի մաս" that is we mentioned the affiliation or փողոց-street on the corner of the street-փողոցի անկյունում or Lilit-Լիլիթ Lilit's bag-Լիլիթի պայուսակը, that is the bag belongs to Lilit if there are any questions, feel free to ask...
