Some features attested in Anatolian presuppose the existence of inherited patterns, such as they may be reconstructed for Proto-Indo-European (i.e. earlier than the split of Proto-Anatolian) on the strength of the evidence from the Core Indo-European languages. The Anatolian forms can thus only be explained in terms of continuity of PIE patterns which have undergone transformations such as remodelling of inherited structures and lexicalization. This is the case with Hitt. mimma-ḫḫi ‘to reject, refuse’, with pippa-ḫḫi ‘to move violently’ and CLuw. ūppa- ‘to carry (off)’, and with Hitt. nakkī- ‘important, prominent’, ‘difficult’, which cannot be explained ex Anatolico ipso and absolutely require a PIE source.
