 One theory about language of the name claim that name "Bač" is of Slavic language, which could be confirmed by the fact that a similar name, "Bača", was recorded among old Russians.In the territory of former Yugoslavia, several similar personal names are recorded among South Slavs too - "Bača", "Bačeta", "Bačić", "Bačko", "Bačun", etc.By the opinion of Milica Grković, the name "Bač" is of Paleo-Balkanic language.
