Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
la letteratura » la litterature, la literatura, e letteratura
de literatura » de litterature, la literatura, y literatura
literatura a » literatura y, literatura e, literatura i
grunde die » grunde der, grunde des, grundlage die
i grain » ii grain
i gran » i grand, i grani, i gram
die la » die lan, die lage, die land

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 gran) OR (i grain)) libro de literatura a ) OR ( i grunde die la letteratura sarda ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((i gran) OR (i grain)) libro de literatura a ) or ( i grunde die la letteratura sarda ))*".
