Perhaps you should try some spelling variations:
massiv » massive
massivieren » massiveieren, passivieren, massivere, massigeren
massieen » massiven, massigen, massigeren
massiger » massinger, massive, massie
passivierender » passivierende, aktivierender, passivieren

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: (massiv OR (massivieren OR ((massieen OR massiger) OR passivierender)))*.
