The word for dog in Hungarian is kutya
. In Hindi/Urdu it is kutta
. I assumed Hungarian had borrowed from Romani, which shares vocabulary with the North Indian languages. But this is not likely since the Romani of that region has a very different word for dog.
Further, I came upon this
site, which, if you search on the page for "kutya" will give you a list of very similar words for dog in Slavic, Caucasian, Afro-Asiatic and other languages.
You can also look at item 72 here
if you read Bulgarian, or just follow Cyrillic.
I paid close attention this morning to the mongrel waifs that hang around my street, and find it hard to believe that onomatopoeia is responsible. One may have been making a "kuch" like sound but I think he was throwing something up. Dogs were domesticated quite some time ago, but is it conceivable that one place, perhaps known for breeding dogs many thousand years ago, contributed the word to other languages?
I'm foxed. Explain.
