Perhaps you should try some spelling variations:
passiv » passive, massiv, passiver
passiverely » passiveerely, massiverely, passivererely, passively, passiverer, passiverwerb
passiven » passiveen, massiven, passiveren, passive, passion
passiviert » passiveiert, massiviert, passiveriert, passioniert, passivieren, passiert
massively » massive
massiven » massive, massiv

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 (passiverely OR massively)) OR (passiven OR massiven)) OR passiviert).
• Adding a wildcard symbol may retrieve word variants: (((passiv or (passiverely or massively)) or (passiven or massiven)) or passiviert)*.
