Perhaps you should try some spelling variations:
letteratura arte » letteratura arti, letteratura sarda, letteratura e
di letteratura » e letteratura, de literatura, della letteratura
ii literatura » ii literature, iii literature, vii literature
ii literatur » vi literatur, viii literatur
grunde fir » grunde fur, grunde der, grunde die
fir di » fir die, fir ii, fur di

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 grunde fir di letteratura arte ) OR ( i grand livre ((ii literatura) OR (ii literatur)) de )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grunde fir di letteratura arte ) or ( i grand livre ((ii literatura) OR (ii literatur)) de ))".
• Adding a wildcard symbol may retrieve word variants: (( i grunde fir di letteratura arte ) or ( i grand livre ((ii literatura) OR (ii literatur)) de ))*.
