Sur ce lien, on peut lire ceci:
Je ne vois pas = I do not see a step (footprint)
Je ne vois point= I do not see a dot
Je ne vois goutte = I do not see a drop
Historically, "ne" (= not) was deemed too weak when used on its own, and the complement (pas, point, goutte) was added as a reinforcement.
Not surprisingly in the country of Descartes, only the step (pas) remained popular over time: if you can't see a step, you obviously can't see a dot or a drop...
So, we now end up with two complements: Je ne vois pas la solution = I do not see a step the solution. Strange, mais c'est la vie.
Est-ce correct ?
