2f administration » csf administration, self administration, delf administration
8 administration » 2008 administration, unis administration
8 administrative » _ administrative, 3 administrative, 4 administrative
22great britain » great britain, xgreat britain, great brittain
zgreat britain » great britain, xgreat britain, great brittain
et colonies » her colonies, des 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: %((22great britain) OR (zgreat britain)) %((((p colonies) OR (_ colonies))) OR (et colonies)) %((((2f administration) OR (((8 administration) OR (8 administrative))))) OR (trf administration))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22great britain) or (zgreat britain)) %((((p colonies) or (_ colonies))) or (et colonies)) %((((2f administration) or (((8 administration) OR (8 administrative))))) or (trf administration))%22".
• Adding a wildcard symbol may retrieve word variants: %((22great britain) or (zgreat britain)) %((((p colonies) or (_ colonies))) or (et colonies)) %((((2f administration) or (((8 administration) OR (8 administrative))))) or (trf administration))%22*.
