Usage Note
Impossible is invariable in form — the same for masculine, feminine, singular, and plural. The phrase c'est impossible is ubiquitous, but French also uses il m'est impossible de (it is impossible for me to) as a more formal construction. The noun l'impossible means 'the impossible' as an abstract concept.
Examples
"C'est impossible de tout faire seul."
Natural Translation
It's impossible to do everything alone.
Literal Translation
It-is impossible of all to-do alone
