bulgaricae » bulgarische, bulgaria, bulgarian, bulgariae, bulgariane, bulgareicae, vulgaricae, bulgariaicae
bulgarica » bulgaria, bulgarisch, bulgarian, bulgareica, vulgarica, bulgariaica

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: ((vulgareiae OR ((bulgareicae OR bulgaricae) OR bulgarica)) OR (bulgar OR bulger))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vulgareiae or ((bulgareicae OR bulgaricae) or bulgarica)) or (bulgar or bulger))*".
