bulgariae » bulgaricae, bulgaria, bulgarian, bulgareiae, vulgariae, bulgariaiae
bulgareiae » bulgaria, bulgarian, bulgaricae, bulgareeiae, vulgareiae, bulgariaeiae
bulgarie » bulgarien, bulgaria, bulgarian, bulgareie, vulgarie, bulgariaie
bulgar » bulgare, vulgar, bulgaria
vulgarisn » vulgaris, vulgarise, vulgarisee

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 bulgareiae) OR bulgarie) OR (((bulgar OR vulgarisn) OR (bulger OR bulge)) OR bulges))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((bulgariae OR bulgareiae) or bulgarie) or (((bulgar or vulgarisn) or (bulger or bulge)) or bulges))*".
