passiv » passive, passiven, passiver
passivene » passiveene, passivenene, passiverene, passiven, passiveand, passiverer
massiv » massive
massivene » massiveene, massiven, massivere, 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 massiv) OR (passivene OR massivene)).
• Adding a wildcard symbol may retrieve word variants: ((passiv or massiv) or (passivene or massivene))*.
