Key words: Indo-European parent language, root *âr-, Slavic languages, diachronic constant, tribes migration.
The article describes the realizations of the Indo-European root *âr- with the meaning ‘аryan’, ’farmer’ which has proved that in Slavic languages the development of this root as PSl. *ôr- (in old ukr. ir-) takes place as opposed to other languages. This typological characteristic of Slavic languages has been analyzed as “diachronic constant” and dominant of Slavic ethnos migration in ancient times, particularly, to Northern Pomor’e, Italy, Iran, India.
