iv letteratura » e letteratura, di letteratura, la letteratura
ii literatura » ii literatur, ii literature, iii literature
grunde libro » grunde fir, und libro
grunde gibt » grund gibt, grunde mit, grunde geht

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 grundei libri iv letteratura sulla ) OR ( i ((grunde libro) OR (grunde gibt)) ii literatura y )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grundei libri iv letteratura sulla ) or ( i ((grunde libro) OR (grunde gibt)) ii literatura y ))".
• Adding a wildcard symbol may retrieve word variants: (( i grundei libri iv letteratura sulla ) or ( i ((grunde libro) OR (grunde gibt)) ii literatura y ))*.
