Nominative
The nominative (eerste naamval) is the most frequent case in Dutch. The following sentence elements always occur in the nominative:
- The subject: Ik ga naar school (I go to school)
- The attribute: Peter is piloot (Peter is a pilot)
- The direct object (only pronouns demand the accusative case): Anja schildert de muur (Anja paints the wall)
- The indirect object (only pronouns demand the dative case): Joop geeft het meisje een ijsje (Joop gives an ice-cream to the girl)
- All other objects are always in the nominative case: Deze maandag is hij niet naar school gegaan (This Monday he didn't go to school)
- The nominative is required after all prepositions, except for the preposition te, fixed expressions and some prepositions with a figurative meaning (only pronouns demand the accusative case): aan de boom (on the tree), door het huis (through the house)
