bulgarian » hungarian, bulgareian, vulgarian, bulgarieian
bulgarica » bulgarisch, bulgarie, bulgareica, vulgarica, bulgarieica
bulgarien » bulgareien, vulgarien, bulgarieien
bulgar » bulgare, vulgar, bulgarie

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: ((bulgariia OR (bulgarien OR (bulgarian OR bulgarica))) OR ((bulgar OR bulgaria) OR bulger))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bulgariia or (bulgarien or (bulgarian or bulgarica))) or ((bulgar OR bulgaria) or bulger))*".
