Perhaps you should try some spelling variations:
letteratura greca » literatura graeca, letteratura fra, literatura grega
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
land letteratura » la letteratura, land literatur, una letteratura
e letteratura » y literatura, e literatur
grundlage die » grundlagen die, grundlage der, grundlage des
grund libro » gran libro, und libro
grunde die » grunde der, grunde des, grundung die
i grund » i grunde, i ground, i grand
libro e » libro de, libero e, libro i

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 greca ) OR ( i ((grunde die) OR (grundlage die)) land letteratura sarda ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grund libro e letteratura greca ) or ( i ((grunde die) OR (grundlage die)) land letteratura sarda ))*".
