communication 5 » communication _, communication a, communication 3
typologies die » typologies _, typologie des, typologie der
development en » developpement en, development menu, development eco
die variation » de variation, does variation, der variation
variation im » variation _, variation 6, variation des
5 leur » a leur
so de » uso de
so we » so wie, do we

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: "typologies die variation im ((so de) OR (so we)) communication 5 leur development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologies die variation im ((so de) OR (so we)) communication 5 leur development en afrique.*.
