Translation:How are you?
Turkish is an agglutinative language... And we usually use hidden subjects. Actually "how are you?" means "sen (hidden subject) nasılsın?". Sen=you (singular), how= nasıl... The suffix "-sın/-sin/-sun etc." adds meaning of "you(singular)" to the words. (Sen) Nasılsın=how are you.(singular, informal) (siz) Nasılsınız=how are you (plural, formal)
There's one thing I've been unable to find for sure. How do I ask for things? food and drink etc. Do I use istiyorum or is that rude. In Spanish you mainly use Want it Can I have. Is there an easy to learn/use phrase that I can add nouns to? Would something ilke 'ben bir kahve istiyorum' ör 'biz bazi yemekleri istiyoruz' work?
Yes, you can say "Ben bir kahve istiyorum." but "Bir kahve (çay/ sandviç/ekmek/pizza etc.) alabilir miyim?" or "Bir kahve, lütfen." is more polite. "Biz bazı yemekleri istiyoruz." is not correct. You may say "Biz tavuk/kuzu şiş/döner istiyoruz." or "Döner alabilir miyiz?". Have a good time in Turkiye!
I have just seen your reply, sorry for that. My English is not good enough but as far as i know, yes, "alabilir miyim" means "can i get" or it may mean "can i buy" if you ask this question in a small grocery for example.
As I said my English is not great so i am not sure i understood correctly but the sentence "we want some food" (Biz biraz yemek istiyoruz) does not make sense (at least for me). I think you must say what you want to eat or what food you want just like"Biz tavuk yemek istiyoruz."
