Questions & Answers about Heb jij iets nodig?
Because it is a yes/no question in Dutch.
In a normal statement, Dutch usually has the subject first:
- Jij hebt iets nodig. = You need something.
In a yes/no question, the finite verb moves to the first position:
- Heb jij iets nodig? = Do you need anything?
So this is a very common Dutch pattern:
- Jij hebt ... → statement
- Heb jij ...? → question
