vulgaris » bulgaria, vulgar
bulgar » bulgare, vulgar, bulger
bulgarien » bulgareien, vulgarien, bulgerien, bulgaria

bulgere » bulgare, bulger, bilgere

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: ((bulgarian OR vulgaris) OR (((bulgar OR (bulgarien OR vulgarien)) OR bulgere) OR (bulges OR bulge)))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bulgarian or vulgaris) or (((bulgar or (bulgarien or vulgarien)) or bulgere) or (bulges OR bulge)))*".
