This page is confusing me a little. At the bottom there is a list of verbs and phrases which take both the subjunctive and the ne explétif.
Apparently nier and douter only take the ne explétif when there are negative implications involved, but then why are they in the list in the first place? Surely the vast majority of verbs and phrases indeed only take 'ne' when it's negative.
I know she includes both negative and non negative uses in the page, but I get the impression than she's mainly focusing on the latter...isn't that just pointing out that nier and douter are two of the common French verbs, since all of them can at one point take it correctly?
Or is it because by definition they are negative, so they need to be made "doubly" negative? So to doubt is negative, to deny is negative etc. But then so are verbs like empêcher and it uses the explétif either way.
Sorry if I'm missing an obvious point! Would be grateful for any comments.
