Questions & Answers about Per quanto lei scolleghi il cavo, non può riavviare il dispositivo.
Why is scolleghi in the subjunctive mood here?
The phrase per quanto is a concessive conjunction meaning no matter how much or although. These types of conjunctions introduce a circumstance that doesn't prevent the main action from happening, and they trigger the subjunctive mood in Italian.
Why is there an h in scolleghi when the infinitive is scollegare?
Verbs ending in -gare require an added h in any conjugation where the ending starts with an i or an e. This spelling change preserves the hard g sound of the infinitive. Without the h, the word would be pronounced with a soft sound, like the g in gelato.
Italian usually drops subject pronouns. Why is lei explicitly included?
In the present subjunctive, the conjugations for io, tu, and lui/lei are identical. For this verb, they all become scolleghi. Including the pronoun lei removes the ambiguity so we know exactly who is disconnecting the cable.
Why is the main verb può in the indicative mood instead of the subjunctive?
The subjunctive mood is only triggered inside the dependent clause introduced by per quanto. The main clause stating that she cannot restart the device is a statement of fact, so potere remains in the normal indicative mood.
