bulgariae » bulgaricae, bulgarian, bulgarie, bulgareiae, bulgarieiae
bulgaria » bulgareia, bulgarieia
bulgar » bulgare, bulgarie
bulger » bulge, bulges

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