I guess this would be a pretty simple question to answer. Is this sentence correct:
The player appears to have not connected.
I am having my doubts about the appears to have not part.
P.S.: Not quite sure what tags to put in, feel free to edit.
In the sentence
connected is the focus of negation, and thus not can appear directly before it, as here.
However, not can also appear directly before the beginning of any constituent containing its focus.
Connected is in the Verb Phrase have connected, so not can go before that, too
and also in the Infinitive Complement to have connected, so not can go before that, too
Since appear is a Neg-Raising verb (i.e, it's transparent to negation), not can also negate
the complex VP constituent appears to have been connected.
This, of course, requires Do-Support, because appears is present tense, and negating a tensed verb
requires an auxiliary verb to carry the tense. When there's no auxiliary verb already in the tensed VP to be negated, one uses Do. That's Do-Support; i.e,
They're all grammatical, and they all mean the same thing.
And I didn't even mention A-Raising.
