Questions & Answers about Dein Witz bringt mich immer zum Lachen.
Witz is masculine and here it is the subject of the sentence, so it must be in the nominative case.
For masculine nouns with a possessive like dein, the nominative ending is just the bare form: dein Witz.
- Nominative (subject): dein Witz bringt mich …
- Accusative (direct object): Ich verstehe deinen Witz nicht.
- Dative: Bei deinem Witz musste ich lachen.
So Dein Witz is correct because Witz is the subject.
No. In German you normally don’t use a definite or indefinite article together with a possessive determiner (like mein, dein, sein, ihr, etc.) in front of the same noun.
So you say:
- Dein Witz – your joke
Not: Der dein Witz or Ein dein Witz
The possessive determiner already does the “article job”, so you don’t add another one.
