la literatura » la litterature, a literature
filosofia la » filosofia da, filosofia le, filosofica da
dein studium » ein studium, mein studium, sein studium
dem studium » das studium, im studium, zum studium
a filosofia » la filosofia, e filosofia, di filosofia

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: test ((dein studium) OR (dem studium)) a filosofia la literatura.
• Adding a wildcard symbol may retrieve word variants: test ((dein studium) or (dem studium)) a filosofia la literatura*.
