Questions & Answers about Sans électricité, il fallait se coucher tôt.
Why is il fallait used here instead of il faut?
Il faut is the present tense, meaning "it is necessary" or "you must". Because this sentence describes a general situation or ongoing state in the past ("Without electricity..."), we use the imparfait (imperfect) tense form: il fallait. It translates to "it was necessary" or "one had to".
Why is se coucher in the infinitive (unconjugated) form?
If the translation is "one had to go to bed", why do we use the pronoun se in se coucher?
Because il fallait uses the impersonal il (meaning "it"), it doesn't refer to "me", "you", or "us" specifically. When making a general statement about what people had to do, the reflexive verb keeps its default third-person pronoun, se.
