If PIE originates in Anatolia as has been suggested before, then it should contain lexical material in relationship with Anatolian Neolithic and should share it with other Anatolian and Asianic languages.
As far as sheep are concerned the following items can be reconstructed, especially for Western IE languages:
- *H2owi ‘sheep [generic word]’. This word is shared with Caucasic Nakh *xawxar ‘lamb’ and Hurrian hawurni ‘lamb’. This word has come to apply only to the female in Modern English ewe, but this was not the case in Old English. It is possible that the Nakh word is a compound *xow-ˁaxar ‘lamb of sheep’.
- *H4eri ‘ram [word for adult male]’. This word is shared with Caucasic Nakh *ˀari ‘ram, uncastrated male’.
- *haghwnos ‘lamb’ [mainly a Western IE word]. This word is shared with Caucasic Nakh *ˁaxar ‘lamb’.
