communication 5 » communication _, communication a, communication 3
development en » developpement en, development menu, development eco
typology des » typologie des, typologie der, typology _
variation im » variation 6, variation des, variation 4.1
5 youth » _ youth, a youth, 2 youth
soe 4 » boe 4, ioe 4, sos 4

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 im) OR (variation _)) soe 4 communication 5 youth development en afrique.~".
• Adding a wildcard symbol may retrieve word variants: typology des ((variation im) OR (variation _)) soe 4 communication 5 youth development en afrique.*.
