da literatura » la literatura, a literatura, de literatura
8 filosofia » e filosofia, a filosofia, y filosofia
texto das » text das, texto mas, texten das
studium 8 » studium _, studium 1, studium 3

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: texto das studium 8 filosofia ((pela literatura) OR (da literatura)).
