Perhaps you should try some spelling variations:
passiv » passive, massiv, passiver
passiven » passiveen, massiven, passiveren, passive, passion
passiveeren » passiveeeren, massiveeren, passivereeren, passivieren, passieren, passiverer
passivierung » passiveierung, massivierung, passiverierung, aktivierung
massivere » massiver, massive, massively

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 (passiven OR (massivere OR (passiveeren OR passivierung)))).
• Adding a wildcard symbol may retrieve word variants: (passiv or (passiven or (massivere or (passiveeren or passivierung))))*.
