Perhaps you should try some spelling variations:
communication 3 » communication _, communication a
a developpement » au developpement, de developpement, le developpement
developpement l » developpement il, developpement la, developpement de
des variation » does variation, de variation, der variation
typology des » typologie des, typologie der, typology _
der maske » der marke, der markte, der massen
l afrique » en afrique
der mass » der massen, over mass, air mass

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: "typology des variation _ ((der mass) OR (der maske)) communication 3 a developpement l afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology des variation _ ((der mass) OR (der maske)) communication 3 a developpement l afrique.*.
