German N-Declension: The B2 Guide to Weak Masculine Nouns

N-declension is one of the most reliably tested topics in Goethe B2 — and one of the most commonly forgotten. This guide explains exactly which nouns are affected, how to decline them, and how to avoid the mistakes that cost exam points.

What Is N-Declension?

In standard German noun declension, the article changes but the noun itself stays the same: der Mann → des Mannes → dem Mann → den Mann. A small group of masculine nouns — called weak nouns (schwache Nomen) — behave differently. They add -n or -en in every case except Nominative singular.

So instead of: Ich sehe den Student — you must write: Ich sehe den Studenten. Forget that ending and your sentence is grammatically wrong, which is an automatic point deduction in the Goethe writing exam. The good news: once you know which nouns belong to this group, applying the rule is mechanical.

Declension Table

All weak nouns follow the same pattern. Here it is for der Student:

CaseSingularPlural
Nominativeder Studentdie Studenten
Accusativeden Studentendie Studenten
Dativedem Studentenden Studenten
Genitivedes Studentender Studenten

The rule: add -en everywhere except Nominative singular. A handful of nouns ending in -e in Nominative (like der Junge) add only -n: des Jungen, dem Jungen, den Jungen.

Which Nouns Belong to This Group?

The tricky part isn't conjugation — it's knowing which nouns are weak. The reliable patterns:

One special case: der Name

A small group of weak nouns adds -ns in the Genitive: des Namens, des Herzens, des Friedens, des Willens. These are worth memorising individually since they appear in formal writing.

Example Sentences

der Kunde → den Kunden
Wir helfen dem Kunden sofort.
We'll help the customer right away.
der Kollege → dem Kollegen
Ich arbeite mit einem Kollegen zusammen.
I'm working together with a colleague.
der Mensch → des Menschen
Die Rechte des Menschen müssen geschützt werden.
Human rights must be protected.
der Journalist → den Journalisten
Der Politiker sprach mit dem Journalisten.
The politician spoke with the journalist.
der Zeuge → den Zeugen
Die Polizei befragte den Zeugen.
The police questioned the witness.
der Nachbar → dem Nachbarn
Ich habe meinem Nachbarn geholfen.
I helped my neighbour.

Most Common Mistakes

Forgetting the -en in Accusative. This is the single most frequent error. Learners correctly decline in Dative ("dem Studenten") but write "Ich sehe den Student" instead of "den Studenten". Every non-Nominative singular needs the ending — Accusative included.

Applying N-declension to feminine or neuter nouns. The rule only applies to a specific group of masculine nouns. "die Frau", "das Kind", "die Natur" — these never get the weak ending. When in doubt, check whether the noun is masculine and belongs to one of the suffix patterns above.

Forgetting the Genitive. Because Genitive appears less often in speech, learners often remember Dative and Accusative but blank on "des Studenten". In formal writing — and in Goethe B2 reading texts — Genitive is common.

Study Tips

The most effective way to learn weak nouns is not to memorise a long list but to encounter them repeatedly in real sentences. When you see "dem Kollegen" in a text, don't just note the meaning — note the ending. After a few encounters the pattern becomes automatic.

Use spaced repetition: review a few weak nouns each day rather than cramming the full list once. GermanChunks has dedicated N-declension cards where you see the noun in context and have to recall the correct ending. Cards you miss come back sooner; cards you know well return later.
