Igor is the Russian form of Ingvar, an Old Norse form of Yngvarr from Yngvi, an Old Norse cognate of Ing (the alternate name of the Norse god Frey) possibly meaning “ancestor” combined with the old Norse element arr, herr meaning “warrior” which derives from Proto-Germanic element *harjaz (army; army leader, warrior) so the name would essentially mean “Ing’s warrior” or “Frey’s warrior”.
