Perhaps you should try some spelling variations:
passiv » massiv, passiven, passiver
passive » massive, passivene, passivere
passivere » massivere, passivenere, passiverere, passiverer, passiver
passiverere » massiverere, passivenerere, passivererere, passivererre, passiverre, passiverer, passiverwerb, passivierende

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 ((passive OR passivere) OR passiverere))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(passiv or ((passive OR passivere) or passiverere))*".
