vulgarise » vulgarises, vulgaris, vulgariter
vulgarisee » vulgarisese, vulgarise, vulgaritere, vulgarises, vulgaris, vulgariter
bulgarien » bulgarian

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