my attempt:

From Turkish there is a beautiful expression:

Other than a person´s sweet talk, is there anything nice?

Henry,

When your translation is translated back to Turkish the predicate appears to be "... ne var?"

But the original Turkish sentence is "...nesi var?"

You know this -(s)i is connected with -nın (possessive) in insanın => insanın ... nesi var?

I know your Turkish is almost excellent.. so..

The thing I want to know is: does this possession lose its meaning when translated into English?   

Thank you scalpel, I only wish my Turkish was as good as your English.

I was aware of the connection, ´What is there of a person(´s) ..... other than their sweet talk?´ but I struggled to convert it to an English sentence that I was happy with.

I always remember the Turkish saying:

Bir elin nesi var, iki elin sesi var.

Roughly: What does one hand have, two hands make a sound

So if I used a similar English translation, maybe this would be better ....

What nice things does a person have, other than their sweet talk?

Thanks for making me think harder scalpel, and now I hope the possessive meaning is maintained.
