it is a feature of languages from the area in which the daughter languages of Proto-Anatolian were spoken. Morphology According to Fortson, Proto-Anatolian had two verb conjugations. The first, the mi-conjugation was clearly derived from the familiar Proto-Indo-European present tense endings. The second, the ḫi-conjugation appears to be derived from the Proto-Indo-European perfect. One explanation is that Anatolian turned the perfect into a present tense for a certain group of verbs while another, newer idea is that the ḫi verbs continue a special class of presents which had a complicated relationship with the Proto-Indo-European perfect.
