de letteratura » e letteratura, di letteratura, de litteratura
i literatura » ii literatura, i literature, a literatura
y literatura » la literatura
grand libro » gran libro, grand livre
i grundei » i grunde, i grund
libri de » libro de, libre de, libri duo
i grand » i grunde

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 letteratura sarda ) OR ( i grand libro ((i literatura) OR (y literatura)) de ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grundei libri de letteratura sarda ) or ( i grand libro ((i literatura) OR (y literatura)) de ))*".
