Questions & Answers about È inaccettabile che il prodotto non abbia funzionato. Pretendo un rimborso.
Why do we use the subjunctive in the first sentence?
The phrase è inaccettabile che (it is unacceptable that) is an impersonal expression that shows a strong opinion or judgment. In Italian, these types of expressions trigger the subjunctive mood in the clause that follows.
Why use the past subjunctive (abbia funzionato) instead of the present subjunctive?
We use the past subjunctive to show that the action happened before the main clause. The main clause (è inaccettabile) is in the present tense, but the product's failure happened in the past. The past subjunctive perfectly captures this earlier timeline.
How is the past subjunctive form abbia funzionato built here?
It is made of two parts: the present subjunctive of the helping verb (for avere, the third-person singular is abbia) plus the regular past participle of the main verb (funzionato).
