Questions & Answers about Il faut une signature sur ce document.
Why is il faut translated as "is required" here instead of "must"?
The expression il faut (from the verb falloir) changes its meaning slightly depending on what follows it. If you use it with an action verb, it means "must" or "have to" (like il faut signer, meaning "one must sign"). But when you use it directly with a noun, like une signature, it translates to "needs" or "is required". Literally, the sentence means "It is necessary a signature..."
Since this lesson is about polite requests, how could I make this sentence sound a bit softer?
You can use the conditional tense of falloir! Instead of the present tense il faut (it is necessary), you would say il faudrait (it would be necessary). Saying Il faudrait une signature sur ce document softens the demand, making it sound more polite and less like an order.
Why is it ce document and not cet document?
Could I say Il a besoin d'une signature instead?
Not if you mean "It needs a signature". Avoir besoin de (to need) is generally used for people or animals who "feel" a need. If you start the sentence with Il a besoin..., a French speaker will hear "He needs...". To say that a situation or an object requires something, French strongly prefers the impersonal il faut.
