de letteratura » e letteratura, di letteratura, de litteratura
ii literatura » ii literatur, ii literature, iii literature
i literatura » y literatura, i literature, a literatura
grand libro » grand livre
i grundei » i grunde, i grund

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