apologien de » apologien der, apologia de, apologie des
de variation » der variation, die variation, does variation
des afrique » en afrique, de l'afrique
a does » 4 does, 1 does, 3 does
2 does » 4 does
a des » a der, a das

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: "apologien de variation ((a does) OR (2 does)) _ communication a des developpement des afrique.~".
• Adding a wildcard symbol may retrieve word variants: apologien de variation ((a does) OR (2 does)) _ communication a des developpement des afrique.*.
