Plus Jamais et Jamais Plus

Question

I thought "plus jamais" et "jamais plus" were both acceptable.

Accepted Answer

That's an interesting question, Sean,
In fact, where the 'seul' is placed can change the meaning of the sentence.
If you say -
'et c'est ainsi que notre bûcheron ne se sentit jamais plus seul', meaning he never felt more lonely 
et c'est ainsi que notre bûcheron ne se sentit plus jamais seul = and that's how our lumberjack never felt lonely ever again
and using 'plus jamais' avoids the confusion, so I agree with Aurélie here!

Answer

I've only heard plus jamais for "never again".

Answer

You can say either "plus jamais" or "jamais plus". But plus and jamais always come before rien or personne.https://french.kwiziq.com/revision/grammar/you-can-use-double-andor-multiple-negatives-in-french-negative-expressions

Answer

As Alain points out, the grammar lesson says either is acceptable, but "jamais plus" was marked as wrong when I wrote it.  Putting jamais before plus rien or personne is an easier rule to remember.
