 Proposed by Jay Jasanoff in 1979 and presented in its most elaborate form in Jasanoff (2003), the evidence for the "new" verbal conjugation in PIE is based on the attested existence of the similar ḫi-conjugation in Hittite and other Anatolian languages.Whereas the Anatolian ḫi-conjugation has traditionally been seen as an innovation in the Anatolian branch of the Indo-European family of languages, Jasanoff presents evidence and arguments to place it as a conjugation already established in PIE proper.The following table serves to give an understanding of the problem that the theory tries to solve.
