developpement et » developpement des, developpement de, development east
3 developpement » de developpement, le developpement, et developpement
does variation » de variation, der variation, die variation
theorie does » theorie des, theorie der, theorie die
et afrique » en afrique, l afrique

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: "theorie does variation ((2 its) OR (_ its)) internal communication a 3 developpement et afrique.~".
• Adding a wildcard symbol may retrieve word variants: theorie does variation ((2 its) OR (_ its)) internal communication a 3 developpement et afrique.*.
