Independent subjunctive of doubt (che + subjunctive)

The Independent Subjunctive of Doubt

The subjunctive usually appears in dependent clauses (like penso che...). However, it can stand alone to express deep doubt or ask a rhetorical question.

Start a sentence directly with che followed by the present subjunctive (congiuntivo presente) to mean "Could it be that...?" or "Might it be...?".

Could the investigator have an accomplice?
Che l'investigatore abbia un complice?
Could the robbery be just any theft?
Che la rapina sia un furto qualsiasi?
Could the hostage be poisoned by the accomplice?
Che l'ostaggio venga avvelenato dal complice?

Doubting Past Events

To express suspicion about an event that already happened, use che followed by the past subjunctive (congiuntivo passato).

Could he have forged the alibi?
Che abbia falsificato l'alibi?
Could the investigator have interrogated the hostage?
Che l'investigatore abbia interrogato l'ostaggio?
Could he have hidden the poison after the blackmail?
Che abbia nascosto il veleno dopo il ricatto?

Suspicions vs. Facts

To state confirmed facts rather than suspicions, drop the che and use the standard indicative mood (indicativo).

The investigator interrogated the accomplice.
L'investigatore ha interrogato il complice.
The accomplices poisoned the hostage after the robbery.
I complici hanno avvelenato l'ostaggio dopo la rapina.
