Compound Nouns

Compound nouns consisting of several concatenated nouns and adjectives are a distinguishing feature of the German language and are equivalent to noun clusters in English. Noun clusters decrease the readability and comprehensibility of the text, especially since the relationship between the constituent words is often unclear. Noun clusters can be broken apart by using hyphens and appropriate prepositions to make it clear how these words relate to each other.

Avoid Noun Clusters
