Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
passiviert » passiveiert, massiviert, passiveniert, passioniert, passiert, passiver
passiverer » passiveerer, massiverer, passivenerer, passiverwerb, passiver, passieren
passiveene » passiveeene, massiveene, passiveneene, passiven, passiveand, passivierende
passivierung » passiveierung, massivierung, passivenierung, aktivierung
passivieren » passiveieren, massivieren, passivenieren, passivierende, passieren, passagieren

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 passiviert) OR (passiverer OR (passiveene OR (passivierung OR passivieren)))).
• Adding a wildcard symbol may retrieve word variants: ((passiv or passiviert) or (passiverer or (passiveene or (passivierung or passivieren))))*.
