Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
passivenierung » passiveenierung, massivenierung, passivenenierung, passivierung, passivierungs
passivieren » passiveieren, massivieren, passivenieren, passivierende, passivierung, passieren
massivieren » massigeren, passivierende, passivierung
massivere » massiver, massive, massively
massiveren » massivern, massiven, massivelyn, massigeren, massivement

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 (((massivieren OR massivere) OR passivenierung) OR (massiveren OR passivieren))).
• Adding a wildcard symbol may retrieve word variants: (passiv or (((massivieren or massivere) or passivenierung) or (massiveren or passivieren)))*.
