wife’s sister = görümce

husband’s sister = baldız

brother’s wife = ??

What about brother-in-law? No differentiation?

wife’s brother = kayın, kayınbirader ?

husband’s brother = kayın, kayınbirader ?

sister’s husband = kayın, kayınbirader ?

What is the difference between kayın & kayınbirader? 

Turkish is not an Indo-European language, yet -birader in kayınbirader and -peder in kayınpeder sure look a lot like they´re related to "father" and "brother."

your wife´s sister is baldız not görümce 
husband´s sister is görümce
brother´s wife yenge .
there is nothing special for husband´s brother.
brother in law= kayınbirader,enişte,bacanak,kayın 2) My wife has a brother ı call it kayınbirader and he calls me enişte. 2) my wife has a sister and her sister got a husband her husband calls me bacanak ı call him bacanak we are bacanak : ) it´s too funny to tell these : ) anyway my wife has a sister she calls me kayın as shortening kayınbirader.

sister in law =baldız,elti,görümce  my wife has a sister ı call it baldız.she calls me kayın or enişte both are used. ı have a brother and we are both married our wives call each other elti. ı have a wife and sister my wife calls my sister görümce.


ı´ve married ı call my wife´s father kayınpeder or baba my wife calls my father kayınpeder or baba my wife calls my mother anne or kaynana ı call my wife´s mother kaynana or anne.

yes they re related to birader means brother peder means father  in slang ı call my father sometimes as peder while telling a story to my friends for example but birader used much more. if you need more help please ask or sent me a private message. ı can help you more

Yes, they are related. Related via another indo-euro language: persian. We got these words from persian and persian (farsi) is an indo-european language.
