Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
passivierende » passiveierende, massivierende, passivenierende, passivierender, passivieren, aktivierende
massigeren » massiger, massigen, massierer
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 (passivierende OR (massigeren OR (massivere OR massiver))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(passiv or (passivierende or (massigeren or (massivere OR massiver))))*".
