"Nobody is perfect."

Translation: Personne n'est parfait.

[Lenkvist]

Why isn't it "n'est pas parfait"?

[shimself]

personne means nobody

[Lenkvist]

I knew that, but I didn't realise how it worked together with n'. Thanks for the answer!

"Personne...ne" is one of the negative pairs, including: ne...pas, ne...jamais, ne...plus, etc. The expression "n'est pas parfait" needs the subject which is the other half of "personne...ne" and does not use "pas" at all.

[benh66]

Why is the 'ne' required? Can it be 'personne est parfait'?

[Sitesurf]

Negative expressions are made of two words:

• ne... pas
• ne... plus
• ne... jamais
• aucun... ne
• rien... ne
• personne... ne

In my (limited) experience, the "ne" is dropped in colloquial speech, but it's bad grammar, hence why duo wants you to use it.
