If someone was to ask me - Neredensin?  - where are you from?

And i replied with Ingilteredenim

How would they ask, where abouts?

For my reply to be London etc.

They would ask you - ´Neredesin?´  ( no ´n´ needed there)

You could answer - Ingiltere´den (from England) or just say - Inglizism (I am English) 

Could be ´Nereli?´ or ´Nerede?´

an you could answer ´Londralýyým´ - ´I am a Londoner´ or just ´Londra´dan´

(I hope I´m correct here because this is what I say!)

Thankyouuu!  It is this, my friend told me this before but i had forgotten it.

In fact, "Neredensin?" is the correct form to say "where are you from?" and you reply: -Ýngiltere´denim to say "I´m from England."

"Nerelisin?" (Where are you from as well, but here you are looking for a reply as in the form of "Ýngilizim" (I´m english), so you can consider it as "what nationality are you"

And for a response as "Londra´daným" -I´m from London. or shortly, "Londra´dan"-From London;

-Neresinden? -From which part of it?, or " Neresindensin?"- From which part of it are you from?

or Hangi þehirden? - From which city?

So I´m wrong all the time when I speak to people?  I wish they would correct me

 I don´t know if you are wrong all the time.

You can answer directly with the city name as well as  "Londralýyým "to "Nerelisin?"

or "Londra´daným" to "Neredensin?"

But....can you just say ´Londra´dan´ because in English if someone asked me where I was from I would be more likely to just say ´from London´ than ´I am from London´ - or doesn´t that follow in Turkish?  People say lots of things in a short way.  If someone asks me ´nasýlsýn´ I usually answer ´teþekkurler - ya sen?´ now. I don´t do the whole ´Iyiyim teþekkur ederim, sen nasýlsýn´ thing I was taught by the book.

 Yes, you can. Actually, that is what most of the people do

Human nature. We all prefer shorter forms.

In fact you might as well say just "Londra" when you´re asked:

-Neredensin?

-Londra

Ta!!!
