Questions & Answers about Il est demandé de respecter le règlement de la copropriété.
Why use Il est demandé here instead of an active phrase like On demande?
The impersonal passive (Il est demandé) makes the instruction sound highly formal, objective, and official. It removes the person doing the asking, which is standard for rules, signs, and administrative documents. On demande would sound much too conversational for a condominium's official guidelines.
Could we say C'est demandé de respecter... instead of Il est demandé?
Why is there a de between demandé and respecter?
The verb demander requires the preposition de when followed by an infinitive. Even though the verb is flipped into the impersonal passive here, the underlying grammar rule of demander de faire quelque chose (to ask to do something) still applies.
Why is règlement singular in the French sentence but translated as the plural "rules"?
