Look at the way the mother and the child are tied to each other with POSS:

                                  anne|si|nin kuzu|su

There is another way  of that tiedness which is "Ana kuzusu" that means a man who is excessively attached to his mother at an age  when men are expected to be independent (e.g. live on their own, be economically independent) In english it is like "Mother´s boy"
