duales studium » das studium
der filosofica » de filosofia, e filosofica, e filosofia
de literatura » de litterature, y literatura, a literatura
la literatura » la litterature, a literature
tests duales » tests dalekjs, tests des, neues duales

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: "tests duales studium der filosofica ((de literatura) OR (la literatura))*".
