bulgarie » bulgarien, bulgaria, bulgarian
bulgariaian » bulgarian, bulgariia
bulgarica » bulgaria, bulgarisch, bulgarian
bulgare » bulgarien, bulgaria, vulgares
vulgare » vulgar, vulgaris, vulgarly

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 (bulgarie OR ((bulgariaeian OR bulgariaian) OR bulgarica))) OR ((bulgare OR vulgare) OR bulger)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bulgariae or (bulgarie or ((bulgariaeian OR bulgariaian) or bulgarica))) or ((bulgare or vulgare) or bulger))".
• Adding a wildcard symbol may retrieve word variants: ((bulgariae or (bulgarie or ((bulgariaeian OR bulgariaian) or bulgarica))) or ((bulgare or vulgare) or bulger))*.
