literatur greca » literatura graeca, literatura grega, literaturas grecia
grunde fir » grunde fur, grunde der, grunde die
libro e » libro de, libero e, libro i
i gran » i grand, i grain, i grani
fir la » fuir la

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: (( i gran libro e literatur greca ) OR ( i grunde fir la ((literatura sarda) OR (letteratura sarda)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i gran libro e literatur greca ) or ( i grunde fir la ((literatura sarda) OR (letteratura sarda)) ))".
• Adding a wildcard symbol may retrieve word variants: (( i gran libro e literatur greca ) or ( i grunde fir la ((literatura sarda) OR (letteratura sarda)) ))*.
