Since I've recently reread Phoenix, I turned to the bit I remember. In
Chapter 30, page 597: "Cackling madly, he soared through the
school,..., bursting out of blackboards... floating along after
Umbridge..." 
Soaring, bursting out of and floating all suggest ghost to me.

Page 598: Peeves, who was determinedly loosening a crystal chandelier
and could have sworn he heard her tell the poltergeist ... "It screws
the other way."

Now a poltergeist is usually a person, often a teenager if you count a
teenager as a person, who has psychic powers that are disruptive.
Peeves happens to be a ghost who has the powers of a poltergeist. As a
poltergeist, his psychic powers would simply send the chandelier
flying. He wouldn't be trying to unscrew it. Put another way,
unscrewing it implies that he's not a poltergeist. It also implies
that he's too too solid to be a ghost and hence cannot burst out of
blackboards nor soar through the air nor float after Umbridge. Peeves
is a coat of many colours. JKR changes his nature according to what
she wants him to do.
