Proto-Slavic genesis. He points here to a Slavic TarT/TorT (T = any consonant) switch that occurred around 800. Proto-Slavic TorT in East Slavic languages passed into ToroT, so Proto-Slavic *Xorsъ should pass into East Slavic *Xorosъ, and such a notation is not confirmed by the sources. According to him, there is also no reliable attestation of this theonym in West and South Slavic languages. In that case, according to Pukanec, the theonym was borrowed from Persian xuršēt "shining sun", but he does not address the criticism of such etymology by other linguists presented earlier. He also points to another possibility. Proto-Slavic TorT passed into Church Slavonic as TъrT and TrъT, which would explain both notations *Xorsъ and *Xъrsъ and recognizes the *Xъrsъ notation as primary. As the PS *x may derive from PIE *k or *g, when searching for the PIE etymology of the word, attention must be paid primarily to the rounded phones *kʷ, *gʷ, and *gʷʰ; the Proto-Indo-European stem can thus be reconstructed as *kʷr̥s- or *gʷr̥s- or *gʷʰr̥s-. Of the aforementioned stems, only one, *kʷr̥s-, is found in Julius Pokorny's Indogermanisches etymologisches Wörterbuch, who reconstructed this stem using Greek πρῖνος, prînos "oak (holly)", Gaulish prenne "large tree", Old High German horst, hurst "bush, thicket" or Slovene hrást "oak", which, like the theonym in question, contain a vowel between -r- and -s-. Such a reconstruction would indicate functions similar to those of Perun, the god of storms and oaks. Interpretations Khors-Dazhbog – Sun god Scholars who assume an Iranian etymology most often attribute the solar features to Khors. The main argument is the root of the theonim meaning "sun" in the first place, regardless of which exact word that root was. Moreover, according to The Tale of Igor's Campaign, Prince Vseslav, who "came to Tmutarakani before the cocks" and "ran along the road of the great Khors", traveled from west to east and thus reached the castle before the cocks crowed, and in this way "overtook" the Sun. It has also been pointed out in the text of the Primary Chronicle where, when listing the statues of the gods, only between Khors and Dazhbog, the sun god, no conjunction "and" is used (unlike the rest of the gods), and this, according to many scholars, would suggest that Khors is another name of Dadzbog, his hypostasis, or that they are related in some other way. Such a view was
