bulgarian » bulgaria, hungarian, bulgareian, vulgarian, bulgerian
bulgar » bulgare, vulgar, bulger
bulgarie » bulgareie, vulgarie, bulgerie, bulgarien, bulgaria, vulgaris

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 (bulgareia OR bulgarian)) OR ((bulgar OR (bulgarie OR bulgere)) OR bulge))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bulgariae or (bulgareia OR bulgarian)) or ((bulgar or (bulgarie or bulgere)) or bulge))*".
