bulgariae » bulgaricae, bulgarie, bulgarians, bulgareiae, vulgariae, bulgarieiae
bulgarian » hungarian, bulgareian, vulgarian, bulgarieian
bulgarieia » bulgariia, bulgarie, bulgariens, bulgareieia, vulgarieia, bulgarieieia
bulgaria » bulgareia, vulgaria, bulgarieia
bulgar » bulgare, vulgar, bulgarie
bulgarien » bulgareien, vulgarien, bulgarieien

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((bulgariae OR (bulgarian OR (bulgaria OR bulgarieia))) OR (((bulgar OR bulgarien) OR (bulger OR bulge)) OR bulges))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bulgariae or (bulgarian or (bulgaria OR bulgarieia))) or (((bulgar or bulgarien) or (bulger or bulge)) or bulges))*".
