e letterature » e letteratura, et litterature, de litterature
literatura i » literatura y, literatura e, literatura a
libri de » libro de, libre de, libri sex
i grand » i grunde
livre e » livre de, livre en, livre et
i gran » i grain, i grani, i gram

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 ((libri de) OR (libri duo)) literatura i ) OR ( i grand livre e letterature straniere )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i gran ((libri de) OR (libri duo)) literatura i ) or ( i grand livre e letterature straniere ))".
• Adding a wildcard symbol may retrieve word variants: (( i gran ((libri de) OR (libri duo)) literatura i ) or ( i grand livre e letterature straniere ))*.
