To the Question of Slavic-Iranian Language Connections The Iranian-Slavic linguistic correspondences are mainly associated with the migrations of the Cimmerians-Kurds in Europe (see the article Cimmerians .) The vast majority of Iranian loan words don't cover the entire Slavic world, so the researchers tried to bind the words of Iranian origin to one of three traditional Slavic groups – West, East, and South since the Proto-Slavs (PSl) did not have direct contact with the Iranians. However, the two common Slavic words are reconstructed as PSl. ezero "lake" and čepŭ "plug, bung" can have Iranian origin. PSl. čepŭ has been descended by Rus рус. chop, Ukr. Chip, Bulg. chep, Pol. czep, Cz., Slvk. čep a.o. PSl. ezero has matches in the Baltic languages (Lith. ežeras "lake, pond" and Let. ezers the same), which are connected with Arm. ezr "border, edge" [FRAENKEL ERNST. 1962-1965, 125]. However, the source of borrowing for both Slavic and Baltic words is Kurd. zirē "lake", which is connected with Av. zrayō "sea", OPers. draya "sea" [TSABOLOV R.L. 2010: 526]. The original form is preserved in Rus. dial. naziri "on the lake", that is, "on the ziri" [VASMER MAX. 1971. 125]. In the Baltic languages, there are still other borrowings from Kurdish associated with the stay of the Cimmerian Kurds in the Baltic States. Kurds came to the Baltics from Asia Minor through the North Caucasus and Eastern Ukraine. Place names of Kurdish origin indicate that in the east of Ukraine they lingered for a long time, so there should be some borrowings in Ukrainian with Kurdish. Even then, Kurdish had borrowings from the Akkadian language, one of the Semitic languages, which for a long time was the "lingua franca" in the Middle East. The similarity of some Kurdish words to Arabic can be explained by just such borrowings. It is considered commonly that Slavic word meaning "God" is originated from Iranian (PSl bogъ, Bulg, Blr, Crv, Serb, Ukr bog, Polish bóg, Cz. bůh, etc.). Substantiating this statement, the correspondence of Old Persians baga "lord" is given [VASMER MAX. 1964: 181]. In other Iranian languages, except for the Avesta, similar words are absent, therefore V. Abayev suggested that it existed in the "Scythian" language, which he attributed to Iranian [ABAYEV V.I. 1979: 283]. However, A. Brückner rightly notes that there was no contact between the ancient Slavs and Persia, and no one knows whether the Scythians had such a word [BRÜCKNER Aleksander 1927: 34]. Of other Indo-European languages, only Indo-Aryan has a similar word (Old Ind. bhágas "bestowing master"). It cannot be taken into account, because in the Baltic languages another word is used for the concept of God, and Indo-Aryan words could get into Proto-Slavic only through the Balts. If, however, the origin of the word "god" looked in the Aryan languages, then we can consider Kurd. boke "strong, powerful". One of the tribes of the Kurds, the Cimbri, moving to Western Europe from Ukraine, could have contact with the Slavs, who borrowed this word in a generalized sense (see the article Cimbri ") The vast majority of Iranian loan words do not cover the entire Slavic world, so the researchers tried to bind the words of Iranian origin to one of three traditional Slavic groups – West, East, and South. However, at once it became clear that many loan words are characteristic not to one of these groups. The artificial division of the Slavic languages in the mentioned groups was badly tied with neighborhood some Slavic tribes with Iranian ones. Attempts to give some Iranian etymology for common Slavic words with unclear etymology do not seem convincing [HERZENBERG L.G. 1976]. A question how the Iranian loan-words occurred in the western branch of Slavic languages has particular interest. In view of the fact that the Ancient Kurds populated Podolia and a part of eastern Poland before the arrival of the Slavs here, the Kurdish substrate could affect Ukrainian and Polish, and contacts of the Kurds with the ancestors of the Czechs and Slovaks which dwelt in the territory adjacent to the Kurds have left their traces in the languages of these peoples. The Kurdish substrate could affect also the Eastern Slavic languages but of more profound nature as the Left Bank Ukraine was settled by different peoples – the Balts, the Anglo-Saxons, Mordvins before the Slavs. This topic is dealt separately.
