Perhaps you should try some spelling variations:
passiv » passive, passiven, passiver
passivene » passiveene, passivenene, passiverene, passiven, passiveand, passiverer
passivere » passiveere, passivenere, passiverere, passiverer, passiver, passivieren
passivierende » passiveierende, passivenierende, passiverierende, passivierender, passivieren, aktivierende
massivere » massiver, massive, massively, massiveere
massiv » massive

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 ((passivene OR (passivere OR massivere)) OR passivierende)) OR massiv).
• Adding a wildcard symbol may retrieve word variants: ((passiv or ((passivene or (passivere or massivere)) or passivierende)) or massiv)*.
