ii letteratura » e letteratura, la letteratura, ii literatura
di letteratura » e letteratura, de literatura, della letteratura
y literatura » la literatura
grand libro » gran libro, grand livre
i grund » i grunde, i ground
i grand » i grunde
libro y » libro i, libro _, libro e

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