typologie der » typologie des, ideologie der
der variation » de variation, does variation, die variation
ddr 3 » ddr 1, ddr i, der 3
a le » a les, a l, a e

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "typologie der variation _ ddr 3 communication ((a le) OR (a la)) developpement de l'afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie der variation _ ddr 3 communication ((a le) OR (a la)) developpement de l'afrique.*.
