ungarische » ungarischen
bulgarian » bulgaria, hungarian, bulgareian, vulgarian, bulgerian
vulgaria » bulgaria, vulgaris, vulgari
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: ((vulgarie OR ((bulgarische OR ungarische) OR (bulgarian OR vulgaria))) OR ((bulgar OR bulgarie) OR bulge))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vulgarie or ((bulgarische OR ungarische) or (bulgarian or vulgaria))) or ((bulgar or bulgarie) or bulge))*".
