vulgaria » vulgaris, vulgari, vulvaria
bulgarica » bulgarisch, bulgarian, bulgarien, bulgareica, vulgarica, bulgarieica
bulgaria » bulgareia, vulgaria, bulgarieia
bulgar » bulgare, vulgar, bulgarie
bulger » bulge, bulges
bulgese » 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: ((vulgaria OR (bulgarica OR bulgaria)) OR ((bulgar OR bulger) OR bulgese)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vulgaria or (bulgarica OR bulgaria)) or ((bulgar or bulger) or bulgese))".
• Adding a wildcard symbol may retrieve word variants: ((vulgaria or (bulgarica OR bulgaria)) or ((bulgar or bulger) or bulgese))*.
