Perhaps you should try some spelling variations:
passiv » massiv, passiven, passiver
passive » massive, passivene, passivere
passivieren » massivieren, passivenieren, passiverieren, passivierende, passivierung, passieren
massiveren » massigeren, massivement, massiven, massivern, massivelyn
massiveeren » massigeren, massivdecken, massivteilen
massivere » massiver, massive, massively

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