Perhaps you should try some spelling variations:
passiv » passive, passiven, passiver
passiveieren » passiveeieren, passiveneieren, passivereieren, passivieren, passionierten, passivierende
passivenierung » passiveenierung, passivenenierung, passiverenierung, passivierung, passivierungs
massiv » massive
massiven » massiveen, massive, passiven
massively » massiveely, massive
massivieren » massiveieren, passivieren, massivere, massigeren

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 ((massiven OR massively) OR ((passiveieren OR passivenierung) OR massivieren))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((passiv OR massiv) or ((massiven or massively) or ((passiveieren or passivenierung) or massivieren)))".
• Adding a wildcard symbol may retrieve word variants: ((passiv OR massiv) or ((massiven or massively) or ((passiveieren or passivenierung) or massivieren)))*.
