Hey,

I checked the dictionary (Türkiye Türkçesindeki Türkçe Sözcüklerin Köken Bilgisi Sözlüğü, Tuncer Gülensoy) and it is written like this;

neye ~ niye ´Bir olayın sebebini ve amacını sormak için kullanılır´

< ne [> i]+y+e

Nişanyan´s dictionary is not the only source actually. It is popular because it is online. I think TDK should work on this online dictionary issue.  If i will have chance to  check my etymology books i will let you now.  

But  now lets check from another point. 

In Turkey Turkish we are in doubt if  it is coming from ne-y-e or ne diye so let´s check some examples from other Turkic dialects, 

In Turkey Turkish        it is  niye    ne+e (dative)  / or /  ne + diye?

In Uzbek Turkish         it is  nega    ne+ga (dative)

In Kazakh Turkish        it is  неге (nege)   ne+ge (dative)

So above we can see one example from  each dialect group ( Oghuz, Qarluq, Kipchaq ). And according to the other dialect examples,  i think it is clear that niye is coming from ne+e. 

Actually both are ok and proper . But i would say Londra´da ailemle yaşıyorum. 

halturklondon i think there is nothing wrong with your sentence. You don´t have to use "birlikte". 

Doğru  

Andsom that dit dit dit i didn´t hear anymore.  

A different story from my side. I sent a bağlama to USA with PTT for an armenian friend. It reached there earlier than i expected. And bağlama was in a good condition. 

Sen niye ingilizce yazdın ki şimdi  

Hoş geldin  

How can i explain?
