What's the difference between non, ne, and pas?
Non means “no”, as in the answer to a yes/no question.
Ne is an interesting little word, and has many uses, but the basic and most common use is to introduce the negation of a verb. For instance, Je sais = “I know,” Je ne sais pas = “I don’t know.”
Pas, the other half of that negation, basically means “not”. It can be used as “not” without ne, in phrases like pas du tout = “not at all”.
Be careful. Pas has a homonym, a different word that is spelled and pronounced the same way, that means “step”.
