bulgariae » bulgaricae, bulgarian, bulgarie, bulgareiae, vulgariae, bulgarieiae
bulgareia » bulgarian, bulgarie, bulgare, bulgareeia, vulgareia, bulgarieeia

bulgaria » bulgareia, vulgaria, bulgarieia
bulgar » bulgare, vulgar, bulgarie
bulgarien » bulgareien, vulgarien, bulgarieien, bulgarian

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