N-Declension: Weak Nouns

Die n-Deklination

A small group of masculine nouns take an extra -n or -en ending in every case except nominative singular. These are called "weak nouns." Getting this wrong is a very common B1 writing mistake, so it is worth learning as its own pattern rather than folding it into general case endings.

Today's win: correctly decline der Junge and der Name across all four cases.

The pattern

Caseder Junge (boy)der Name (name)
Nominativeder Jungeder Name
Accusativeden Jungenden Namen
Dativedem Jungendem Namen
Genitivedes Jungendes Namens

Only the nominative singular stays unchanged. Every other form adds -n or -en. Name is a slight irregular case: it also adds -s in the genitive (des Namens).

Quick check: "I see the boy" (accusative) - Ich sehe den ______.

Show answer
Jungen

How to recognize a weak noun

Most weak nouns are masculine and refer to people or animals, often ending in -e: der Junge, der Kollege, der Kunde (customer), der Löwe (lion). A second group does not end in -e but still follows the pattern: der Mensch (human), der Herr (gentleman - adds an extra -n: den Herrn), der Student, der Präsident. There is no single rule that predicts every case; a new word must be checked in a dictionary the first time.

Ich arbeite mit einem Kollegen zusammen. (I work together with a colleague. - dative, Kollege becomes Kollegen)
Das ist die Tasche des Studenten. (That is the student's bag. - genitive)

Quick check: which group of nouns is most likely to be weak - masculine nouns ending in -e referring to people, or feminine nouns?

Show answer
masculine nouns ending in -e referring to people

Full case table and a longer list: Reference - N-Declension.

Quick check: what extra letter does "Herr" add on top of the usual -n pattern in the accusative/dative?

Show answer
nothing extra - it just becomes "Herrn" (still just -n)
Try it out loud: say "I am talking with my colleague" and "I see the neighbor" out loud, using the correct weak-noun ending.
