Perhaps you should try some spelling variations:
passiv » massiv, passiven
passivee » massivee, passivenee, passiven, passives, passivem
passiver » massiver, passivener, passiven, passively, passiert
passive » massive, passivene
passiveerer » massiveerer, passiveneerer, passivenrer, passivesrer, passivemrer, passiverer, passivieren, passiverwerb

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