Perhaps you should try some spelling variations:
passiv » passive, massiv, passiven
passivieren » passiveieren, massivieren, passivenieren, passivierende, passivierung, passieren
massiveren » massigeren, massivement, massiven, massivelyn, massivenn, massiveen, massivenen, passiveren
massiveeren » massigeren, massivdecken, massivteilen
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 (massiveren OR (massiveren OR ((massiveeren OR (massivere OR massiver)) OR passivieren)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(passiv or (massiveren or (massiveren or ((massiveeren or (massivere OR massiver)) or passivieren))))".
• Adding a wildcard symbol may retrieve word variants: (passiv or (massiveren or (massiveren or ((massiveeren or (massivere OR massiver)) or passivieren))))*.
