Questions & Answers about Prima di iniziare, si deve leggere il regolamento.
Why is it si deve leggere instead of just deve leggere?
If we changed il regolamento (the regulation) to le regole (the rules), would the verb change?
This lesson is about chiunque (anyone/whoever). Could I use chiunque here instead of the impersonal si?
You could express a similar idea, but it requires changing the sentence structure entirely. Chiunque acts as a pronoun meaning 'anyone who' or 'whoever', and it usually triggers the subjunctive when setting a condition. You would have to say something like: Chiunque voglia iniziare deve leggere il regolamento (Whoever wants to start must read the regulation).
Why is iniziare in the infinitive here?
In Italian, the phrase prima di (before) is always followed by an infinitive verb when the subject doing the action is the same as the main clause, or when the sentence is a general, impersonal statement like this one.
