Perhaps you should try some spelling variations:
passiv » passive, massiv, passiver
passiven » passiveen, massiven, passiveren, passive, passion
passiveen » passiveeen, massiveen, passivereen, passiveand, passiverer, passive
passivieren » passiveieren, massivieren, passiverieren, passivierende, passivierung, passieren
passivierender » passiveierender, massivierender, passiverierender, passivierendeder, passivierungder, passierender, passivierende, aktivierender
massiven » massive, massiv
massively » 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 (passiven OR passiveen)) OR ((massiven OR massively) OR (passivieren OR passivierender))).
• Adding a wildcard symbol may retrieve word variants: ((passiv or (passiven or passiveen)) or ((massiven or massively) or (passivieren or passivierender)))*.
