Perhaps you should try some spelling variations:
litterature sarda » letteratura sarda, litterature par, litterature serbe
la litterature » a literature
e letteratura » e literatur
y literatura » la literatura
grund libro » gran libro, und libro
grunde die » grunde der, grunde des, grundlage die
i grund » i ground, i grand
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 grund libro ((e letteratura) OR (y literatura)) fra ) OR ( i grunde die la litterature sarda ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grund libro ((e letteratura) OR (y literatura)) fra ) or ( i grunde die la litterature sarda ))*".
