y literatura » la literatura
des studium » des studiums, das studium, dem studium
5 filosofia » a filosofia, y filosofia, _ filosofia
e filosofia » la filosofia
its des » its de, edits des, its debts

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "its des studium ((5 filosofia) OR (e filosofia)) y literatura".
• Adding a wildcard symbol may retrieve word variants: its des studium ((5 filosofia) OR (e filosofia)) y literatura*.
