FAQ about N declension endings

What is the main idea of N declension?
Certain masculine nouns add an ending in all cases except nominative singular. In this quiz you decide whether the sentence needs no ending, n, or en. For a full explanation with examples, read the N Deklination article.
When is no ending the correct choice?
No ending is correct in nominative singular, when the noun is the subject as in Der Junge kommt. Many learners add an ending too early, so always check who does the action first.
How do I decide between n and en?
Both appear in this noun group, but each noun follows its own pattern. Many nouns ending in e take n, while many other weak nouns take en, such as Student or Polizist. Practice helps you build quick recognition in real sentences.
Why is this topic connected to cases?
The ending changes because the case changes, for example after articles like dem, den, or des. If cases still feel unclear, review German cases and then return to this exercise.
