It means "not"
'Not' in French is 'Pas'
The word 'oublier' means forget. Putting the word 'pas' in front of it reverses the meaning - to 'remember'. The literal translation of 'pas oublier' is 'not forget'
Pas means 'Not'.
"ne traverse pas" is the French translation for the English word "trespass". That would be an acceptable equivalent.
Non is the word for no in French. If you're trying to say "we have no _____" then the word is ne pas aucun. Example: We don't have no apples."Nous n'avons pas aucune pomme."
I can not would be : je ne puis pas you can not : vous ne pouvez pas.
"Does not" in French is usually expressed with the word "ne...pas." For example, "he does not" would be translated as "il ne fait pas."
au pas
tu ne parles pas français mean : you don't speak French
remarks on "je ne pas de sour": there is no verb in that sentence, and sour is not a French word. I gather that you mean "je n'ai pas de sous" which means familiarly "I have no money"
tu n'es pas gentil, pas gentille
Pas mal means 'not bad' in French.
