literatura en » literatura y
grunde libro » grunde fir, grunde gibt, und libro
i literatura » ii literatura, y literatura, i literature
i grundei » i grund
libri de » libro de, libre de, libri sex
libro i » libro di, libro de

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 grundei ((libri de) OR (libri duo)) letteratura sarda ) OR ( i grunde libro i literatura en )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grundei ((libri de) OR (libri duo)) letteratura sarda ) or ( i grunde libro i literatura en ))".
• Adding a wildcard symbol may retrieve word variants: (( i grundei ((libri de) OR (libri duo)) letteratura sarda ) or ( i grunde libro i literatura en ))*.
