bulgaricae » bulgarica, bulgarische, bulgaria, vulgaricae, bulgericae, bulgariaicae
bulgarieia » bulgariia, bulgaria, bulgarien, vulgarieia, bulgerieia, bulgariaieia
bulgar » vulgar, bulger, bulgaria

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 bulgaricae) OR bulgarieia) OR ((bulgar OR bulgare) OR bulge))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((bulgariae OR bulgaricae) or bulgarieia) or ((bulgar or bulgare) or bulge))*".
