y literatura » la literatura
studium des » studium der
filologia y » filologia e, filologica e, filosofia y
texto das » texto mas, texten das, texto de
text das » text des, text data, text der

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: "((texto das) OR (text das)) studium des filologia y literatura".
• Adding a wildcard symbol may retrieve word variants: ((texto das) OR (text das)) studium des filologia y literatura*.
