Perhaps you should try some spelling variations:
passiv » massiv, passiven, passiver
passive » massive, passivene, passivere
passivierung » massivierung, passivenierung, passiverierung, aktivierung
massivere » massiver, massive, massively
massiveren » massivern, massiven, massivelyn, massigeren, massivement, passivieren
massiveeren » passivieren, massigeren, massivdecken

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