bulgaria » vulgaria, bulgarieia
bulgar » vulgar, bulgarie
bulgare » vulgare, bulgariee, bulgarie, bulgarien
bulger » bulges
bilgere » bilger, bilgeri, billigere

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: ((bulgaria OR bulgarieiia) OR (((bulgar OR bulgare) OR bulger) OR (bulge OR bilgere))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bulgaria or bulgarieiia) or (((bulgar OR bulgare) or bulger) or (bulge or bilgere)))".
• Adding a wildcard symbol may retrieve word variants: ((bulgaria or bulgarieiia) or (((bulgar OR bulgare) or bulger) or (bulge or bilgere)))*.
