Questions & Answers about Zij heeft noch een bed noch een stoel nodig.
Why don't we use geen (no) before bed and stoel to make them negative?
Why is the word nodig placed at the very end of the sentence?
In Dutch, "to need" is expressed with the combination nodig hebben. In a standard main clause, the conjugated verb (heeft) takes the second position, while nodig is pushed all the way to the end, after the objects (noch een bed noch een stoel).
Could I just say Zij heeft geen bed en geen stoel nodig instead?
Yes, that is a perfectly natural and actually more common way to express this in everyday spoken Dutch. Using noch ... noch is a bit more formal, exactly like choosing "neither ... nor" over "doesn't need a bed or a chair" in English.
Does starting with Zij instead of Ze change the feeling of the sentence?
Yes, using the stressed pronoun Zij puts a little extra emphasis on the subject. It often implies a contrast, suggesting "She doesn't need a bed or a chair (but perhaps someone else does)."
