transform la » transform a, transformar la, transform _
de leaders » e leaders, few leaders, 1 leaders
3 leaders » _ leaders, 3 leader, e leaders
guia der » guia de, aura der, guia do

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: (( vague ((de leaders) OR (3 leaders)) transform la acao ) OR ( guia der a transformed _ acao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( vague ((de leaders) OR (3 leaders)) transform la acao ) or ( guia der a transformed _ acao ))~".
• Adding a wildcard symbol may retrieve word variants: (( vague ((de leaders) OR (3 leaders)) transform la acao ) or ( guia der a transformed _ acao ))*.
