To describe the structure of a system, the UML Class Diagram yields the means-of-choice. Therefore, the Class Diagram provides concepts like class, attribute, operation, association, generalization, aggregation, enumeration, etc. When students are introduced to this diagram, they often have to solve exercises where texts in natural language are given and they have to model the described systems. When analyzing such exercises, it becomes evident that certain kinds of phrases describing a particular concept appear again and again contextualized to the described domain.
