Perhaps you should try some spelling variations:
passiv » passive, massiv
passiver » passiveer, massiver, passive, passively, passiert
passiviert » passiveiert, massiviert, passioniert, passivieren, passiert
passiven » passiveen, massiven, passive, passion
massiver » massive, massiven, massively
massiveene » massivement, massiven, massivere

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: ((passiv OR ((passiver OR massiver) OR passiviert)) OR (massiveene OR passiven)).
• Adding a wildcard symbol may retrieve word variants: ((passiv or ((passiver or massiver) or passiviert)) or (massiveene or passiven))*.
