Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
massiveren » massigeren, massivement, passivieren, massivern, massiven, massivelyn
massiveeren » passivieren, massigeren, massivteilen
massivdecken » massivbrucken
massivere » massiver, massive, massively
passieren » passiert, passiven

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