bulgar » bulgare, vulgar, bulgaria
bulgarie » bulgareie, vulgarie, bulgariaie, bulgarien, bulgaria, bulgarian
bulger » bulges
bulgere » bulgese, bulgare, bilgere, burgere

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