e letteratura » e literatur
y literatura » la literatura
grain libro » grain fibril
i grain » ii grain
libro e » libro de, libero e, libro i
i gran » i grand, 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 grain libro ((de literatura) OR (y literatura)) artes ) OR ( i gran libro e letteratura sarda )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grain libro ((de literatura) OR (y literatura)) artes ) or ( i gran libro e letteratura sarda ))".
• Adding a wildcard symbol may retrieve word variants: (( i grain libro ((de literatura) OR (y literatura)) artes ) or ( i gran libro e letteratura sarda ))*.
