*bogъ Perunъ

Identical with Etymology 1. According to consensus, a semantic loan from Scythian languages. Zoroastrianism, the new religion of the Iranians, demonized the original pagan deities (compare Sanskrit देव (deva, “god”) : Avestan 𐬛𐬀𐬉𐬎𐬎𐬀‎ (daēuua, “demon”)). During the so-called Iranian inversion (Proto-Slavic-Iranian contacts), the same religious changes took place among the Proto-Slavs and the original word (*deiwos or similar) for “god” was replaced by *bogъ. The change of meaning on Iranian ground was as follows: “wealth” > “wealth provider” > “god”. See also *divъ.

Semantic cognates include Old Persian 𐏎 (BG /baga/, “god”), Avestan 𐬠𐬀𐬖𐬀‎ (baγa, “god”).
