You are not responsible for that because you are a Serb. Everyone is responsible only for their own actions.

Nice try. I will correct your mistakes later. Maybe others would like to translate it too.

Maybe r has a different sound concept in your language. It is possible.

Thank you. You are so kind

I guess I have an explanation:

onların ev-i : their home

This -i is possesive suffix for third person singular (o).

But as you can see we can use it for third person plural (onlar) too

So I think maybe we should think that -lar is plural suffix and -ı is possive suffix (for third person singular) when we use "ları" for more than one possession. That way maybe we can explain why we dont say "larlari".

Note: I am not sure

A nice verse from Necip Fazıl Kısakürek about nihility from his poem Çile. 
I like it a lot.

Ateşten zehrini tattım bu okun,

Bir anda kül etti can elmasımı.

Sanki burnum, değdi burnuna "yok"un,

Kustum öz ağzımdan kafatasımı.

I tasted fiery poison of this arrow
In a blink it turned my jewel of heart into ash.
As if my nose had touched the nose of nihility
I threw up my skull from my own mouth.

Yes you cant write "lerleri"

I recommend you yoga 

Her?
