The linguist had proved that Sanskrit split from avistan and entered India.
According to Anthony, the following terminology may be used:
[2]
- Early PIE for "the last common ancestor of the Anatolian and non-Anatolian IE branches";
- Post-Anatolian PIE for "the last common ancestor of the non-Anatolian PIE languages, including Tocharian";
- Late PIE for "the common ancestor of all other IE branches."
The Anatolian languages are the first Indo-European language family to have split off from the main group. Due to the archaic elements preserved in the Anatolian languages, they may be a "cousin" of Proto-Indo-European, instead of a "daughter," but Anatolian is generally regarded as an early offshoot of the Indo-European language group.

The
Indo-Hittite hypothesis postulates a common predecessor for both the Anatolian languages and the other indo-European languages, called Indi-Hittite or Indo-Anatolian.
[2]Although it's obvious that PIE had predecessors,
[13] the Indo-Hittite hypothesis is not widely accepted, and there is little to suggest that it is possible to reconstruct a proto-Indo-Hittite stage that differs substantially from what is already reconstructed for PIE.
