oral communication » personal communication
developpement la » developpement de, developpement et, developpement du
typologie die » typologie des, typologie der, theologie die
die variation » de variation, does variation, der variation
variation 6 » variation _, variations _, variation des
la afrique » l afrique, la fabrique, en afrique
a oral » _ oral, 2 oral, 4 oral
a des » a der, a das
a de » a die, a der, _ de

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 die variation 6 a oral communication ((a de) OR (a des)) developpement la afrique.~".
• Adding a wildcard symbol may retrieve word variants: typologie die variation 6 a oral communication ((a de) OR (a des)) developpement la afrique.*.
