Perhaps you should try some spelling variations:
massiv » massive
massivere » massiveere, massive, massively, massiven, massivee, massivene, massivelye
massiveer » massiveeer, massive, massively, massiven
massiver » massiveer, massive, massiven, massively
passiver » passiven, passively, passiert

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 ((passive OR massivere) OR ((passiver OR massiveer) OR massiver))).
• Adding a wildcard symbol may retrieve word variants: (massiv or ((passive or massivere) or ((passiver or massiveer) or massiver)))*.
