Genitive case
The genitive case is used to denote ownership. In English, we use the "apostrophe s" or prepositions to do this. German speakers can also use prepositions and frequently do so for spoken language.
However, genitive case markers are used extensively in written German. In addition to affecting articles, pronouns, and adjectives, with masculine and neuter nouns, an –es or –s ending is also added to the noun.
In these exercises, you will practice using genitive case markers.
