Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
land letteratura » la letteratura, land literatur, una letteratura
e letteratura » y literatura
grund libro » gran libro, und libro
grunde die » grunde der, grunde des, grundlage die
die land » die lander, die lange
i grund » i ground, i grand

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 grund libro ((e letteratura) OR (e literatur)) greca ) OR ( i grunde die land letteratura sarda )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grund libro ((e letteratura) OR (e literatur)) greca ) or ( i grunde die land letteratura sarda ))".
• Adding a wildcard symbol may retrieve word variants: (( i grund libro ((e letteratura) OR (e literatur)) greca ) or ( i grunde die land letteratura sarda ))*.
