Whose (Wessen)

Level 4

Wessen is the genitive form of the interrogative pronoun wer. It translates to 'whose' in questions (Wessen Buch ist das?) or 'whoever's' in formal, headless relative clauses (Wessen Brot ich ess...).

How It Works

To use wessen correctly, you must distinguish between its two main roles:

1. Interrogative Pronoun (Questions)
This is the most common use. It asks about possession in both direct and indirect questions. In modern German, the noun after wessen can be a person or a thing. Unlike other German pronouns like welcher or dieser, wessen is invariant; it does not change its ending to match the gender or number of the possessed object.

The 'No Article' Rule: Crucially, the noun following wessen does not take an article. You say Wessen Buch, never Wessen das Buch.

  • Wessen Auto ist das? (Whose car is that?)
  • Wessen Motor ist kaputt? (Whose motor is broken?)
  • Ich weiß nicht, wessen Idee das war. (I don't know whose idea that was.)

Spoken Alternatives: In casual speech, Germans often avoid the genitive wessen by using dative constructions like Wem gehört...? (To whom does... belong?) or Von wem ist...? (From whom is...?).

2. Free Relative Pronoun (Headless Relatives)
In formal or literary German, wessen introduces a relative clause that has no specific antecedent (no noun before it). It often starts the sentence and is frequently followed by a correlative pronoun in the main clause. This correlative pronoun (der, die, das, dem, etc.) must match the case required by the verb in the main clause.

  • Wessen Herz voll ist, dem läuft der Mund über. (Whose heart is full, his mouth overflows. — 'dem' is dative because of 'laufen')

3. The 'Headed' Restriction
Crucially, wessen cannot be used to modify a specific noun in a standard relative clause. For that, you must use the genitive relative pronouns dessen (masculine/neuter) or deren (feminine/plural).

  • Incorrect: Der Mann, wessen Hund...
  • Correct: Der Mann, dessen Hund...

  2. Wessen Brot ich ess, dessen Lied ich sing.

    Whose bread I eat, his song I sing.

    Word by Word: Whose bread I eat, whose song I sing.

    A famous proverb showing 'wessen' as a free relative pronoun. It doesn't refer to a specific person mentioned earlier.

  3. Die Polizei fragte, wessen Fingerabdrücke das waren.

    The police asked whose fingerprints those were.

    Word by Word: The police asked, whose fingerprints that were.

    An indirect question using 'wessen' after a verb of communication (fragen).

  4. Wessen Haus am Waldrand steht, der hat viel Ruhe.

    Whoever's house stands at the edge of the forest has a lot of peace.

    Word by Word: Whose house at-the forest-edge stands, he has much peace.

    A formal relative construction where 'wessen' acts as 'the person whose'.

Common Mistakes

  • Using 'wessen' in a headed relative clause.

    Das ist die Frau, wessen Auto gestohlen wurde.
    Das ist die Frau, deren Auto gestohlen wurde.

    When referring back to a specific noun (die Frau), you must use 'dessen' or 'deren'. 'Wessen' is only for questions or 'headless' relatives.

  • Confusing 'wessen' with 'wem' (dative).

    Wem Buch ist das?
    Wessen Buch ist das?

    Learners sometimes use the dative 'wem' (to whom) when they mean the genitive 'wessen' (whose) to show possession.

  • Including an article after 'wessen'.

    Wessen das Auto ist das?
    Wessen Auto ist das?

    The noun following 'wessen' never takes an article. 'Wessen' already functions as the determiner for that noun.
