del learners » all learners, efl learners, do learners
transfer a » transfer _, transfer 3, transfer 4
aguas del » aguas de, aguas do
ist mann » ist dann, test mann, ist denn
guias de » guia de, guide de, aguas de
a macao » a macro, _ macao

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: (( aguas del learners transform ist mann ) OR ( ((guias a) OR (guias de)) heat transfer a macao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas del learners transform ist mann ) or ( ((guias a) OR (guias de)) heat transfer a macao ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas del learners transform ist mann ) or ( ((guias a) OR (guias de)) heat transfer a macao ))*.
