Questions & Answers about Ich wasche dem Baby den Dreck vom Ärmel.
Why is dem Baby used here instead of a possessive phrase like von seinem Ärmel?
This is the possessive dative. In German, when you do something to someone's body part or piece of clothing, you usually put the person in the dative case (dem Baby) and use a definite article with the item itself (here, the m in vom). It sounds much more natural to a native speaker than using a possessive pronoun.
Could I use the genitive case and say Ich wasche den Dreck vom Ärmel des Babys?
Yes, that is grammatically correct and means exactly the same thing. However, at a B2 level, it is important to know that Germans strongly prefer the possessive dative for body parts and clothing. The dative structure feels more personal because it shows that the baby is directly affected by the action.
Why is the word Dreck in the accusative case (den Dreck)?
Because Dreck (dirt) is the direct object of the sentence. It is the thing that you are actively washing. While the baby gets the dative case to show whose sleeve it is, the dirt gets the accusative because it receives the action of the verb waschen.
Does the preposition von in vom take the dative case because of the possessive dative rule?
