information i » information im, information 2, information 1

2 areal » 2 real, _ areal, 2 areas

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: "technologien des information i ((die den) OR (die der)) communication costs 3 development 2 areal.~".
• Adding a wildcard symbol may retrieve word variants: technologien des information i ((die den) OR (die der)) communication costs 3 development 2 areal.*.
