2f administration » trf administration, self administration, delf administration
des colonies » her colonies, _ colonies
et colonies » her colonies, les colonies, ant colonies
p colonies » _ colonies, her colonies, les colonies

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %great britain %((p colonies) OR (((et colonies) OR (des colonies)))) %((2f administration) OR (csf administration))%22.
• Adding a wildcard symbol may retrieve word variants: %great britain %((p colonies) or (((et colonies) or (des colonies)))) %((2f administration) or (csf administration))%22*.
