[Verginius Rufus]

Kurdish is also an Indo-European language (of the same branch as Persian).

The Hittite word for "water" was watar. Their word for "knee" was genu, the same as the Latin word. But the majority of the vocabulary is said to be of non-Indo-European origin. Some of the inflections resemble those in Greek and Latin rather closely.

Yep on the Kurdish. My understanding is that the Anatolian branch split off before any other. I read a real good book on it recently called “The Horse, the Wheel and Language: How Bronze-Age Riders from the Eurasian Steppes Shaped the Modern World “ by David W. Anthony. It was very good (I have read quite a few books on this subject) and found this one to be the best one so far.
