Questions & Answers about Era impossível que a queda do império tivesse acontecido tão depressa.
How is the Pluperfect Subjunctive tivesse acontecido formed in this sentence?
It is formed by combining the auxiliary verb ter in the Imperfect Subjunctive (tivesse, matching the third-person singular for a queda) with the past participle of the main verb (acontecido).
Why do we need the subjunctive mood here instead of saying tinha acontecido?
The phrase Era impossível que acts as an impersonal expression of doubt or subjectivity. Just like in the present tense, where É impossível que triggers the Present Subjunctive, setting this trigger in the past requires a past subjunctive form in the dependent clause.
Why use the Pluperfect Subjunctive (tivesse acontecido) instead of just the Imperfect Subjunctive (acontecesse)?
We use the Pluperfect Subjunctive because the action of the empire falling happened before the past moment when it was considered impossible. If you used acontecesse, it would mean it was impossible for the fall to happen at that same time, whereas tivesse acontecido correctly translates to 'had happened', showing that the event was already complete.
Could I use the auxiliary verb haver instead of ter and say houvesse acontecido?
