Questions & Answers about Dopo la preghiera, ci si è seduti in silenzio con devozione.
Why do we use ci si here instead of just si for 'one sat down'?
Since the subject is the impersonal 'one', why is the past participle seduti in the plural instead of the singular seduto?
This is the core rule for the impersonal si and ci si in compound tenses. Whenever the verb takes essere as its helping verb—which all reflexive verbs do—the past participle must take the masculine plural ending -i. Even though 'one' feels singular in English, Italian requires the plural seduti here.
Could we use avere as the helping verb and say ci si ha seduti?
No, you must use essere here. Reflexive verbs like sedersi always take essere in compound tenses. Making the verb impersonal doesn't change this underlying rule, so the helping verb remains è.
