Introduction
In German, noun cases play a crucial role in determining the function of a noun within a sentence. The nominative, accusative, and dative cases each have distinct uses and forms, affecting both nouns and their accompanying articles. Understanding these cases is essential for constructing grammatically correct sentences.

Nominative Articles

| Feminine | die | eine |
| Neuter | das | ein |
