Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
passivieren » passiveieren, massivieren, passivenieren, passivierende, passivierung, passieren
passively » passiveely, massively, passivenely, passive, passivity, passiven
passiver » passiveer, massiver, passivener, passive, passiven, passiert
massiven » massive, passiven, massiv
massively » massive

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 ((passivieren OR massiven) OR (passively OR (passiver OR massively)))).
• Adding a wildcard symbol may retrieve word variants: (passiv or ((passivieren or massiven) or (passively or (passiver or massively))))*.
