Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
passivierung » passiveierung, massivierung, passivenierung, aktivierung
massivere » massiver, massive, massively
massiveren » massivern, massiven, massivelyn, massivement, passivieren
massiveeren » passivieren, massivdecken, massivteilen
massigeren » massiger, massigen, massierer

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