Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
passiveere » passiveeere, massiveere, passiveneere, passivieren, passiver, massivere
passivierender » passiveierender, massivierender, passivenierender, aktivierender, passivieren, passivierenr, passivierungr
passivierende » passiveierende, massivierende, passivenierende, passivieren, aktivierende, passivierung

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 passiveere) OR (passivierender OR passivierende)).
• Adding a wildcard symbol may retrieve word variants: ((passiv or passiveere) or (passivierender or passivierende))*.
