Perhaps you should try some spelling variations:
passiv » massiv, passiver
passivere » massivere, passiverere, passiverer, passiver, passivieren
passive » massive, passivere
passiven » massiven, passiveren, passion
massivene » massiven, massive, massively
massivere » massive, massively, massiven, massivee, massivene, passivere
massiver » massive, massiven, passiver

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 (massivene OR massivere)) OR ((passivere OR massiver) OR (passive OR passiven))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((passiv or (massivene OR massivere)) or ((passivere or massiver) or (passive or passiven)))".
• Adding a wildcard symbol may retrieve word variants: ((passiv or (massivene OR massivere)) or ((passivere or massiver) or (passive or passiven)))*.
