Questions & Answers about Der Brief blieb ungelesen, worüber sie sehr traurig war.
Is blieb ungelesen a form of the passive voice?
It is closely related to the state passive (Zustandspassiv), which usually uses sein plus a past participle. By using bleiben instead of sein, and adding the un- prefix to the participle (ungelesen), you emphasize that an expected action did not happen and that this undone state persisted over time.
Why is worüber used here instead of a normal relative pronoun like über das?
The word worüber does not refer to a specific noun like the letter; it refers to the entire previous clause, which is the fact that the letter remained unread. When you want to say 'about which' referring back to a whole idea or sentence, you use a wo- compound, which here is wo plus r plus über.
How do we know to use über as the base for worüber?
The preposition is dictated by the adjective in the second clause. In German, you are sad about something using the phrase traurig sein über. Because this preposition links the sadness to the first clause, über merges with wo- to form worüber.
Can I add the un- prefix to the past participle of any verb to use with bleiben?
