Questions & Answers about Ele é culpado, mas já escondeu a prova.
Why do we use é (from ser) instead of está (from estar) for being guilty?
I know a prova translates to "the proof" here. Does it have other common meanings?
Yes! While in a legal or investigative context it means "proof" or "evidence", in everyday life a prova is frequently used to mean a "test" or "exam" at school or university.
We are currently learning the Future Subjunctive. Since this sentence states a past fact, it uses the regular past tense (escondeu). How would this verb look if the sentence was a future possibility, like "If he hides the proof"?
To say "If he hides the proof", you would use the Future Subjunctive (Futuro do Conjuntivo). Because esconder is a regular verb, its Future Subjunctive form is identical to its personal infinitive: se ele esconder a prova.
