how can i use it?
i got two examples
il faut une carte d´identite



il faut un parapluie car il pleut= they/you/i must a umbrella because must rain

what it means?
help me please

Hello, 'Il faut' is better translated with "It's obligatory", so :

Il faut une carte d'identité = It's obligatory to have an id (card)

Il faut un parapluie car il pleut = It's obligatory to have un umbrella because it's raining (it rains)

I hope it's clear for you.
