Fans respect the Phantom (7)
I believe the answer is:
spectre
'the phantom' is the definition.
(spectre is a kind of phantom)
'fans respect' is the wordplay.
'fans' is an anagram indicator (I've seen 'fan' mean this (letters must be fanned around)).
'respect' is an anagram of 'SPECTRE'.
(Other definitions for spectre that I've seen before include "Sceptre (anag.)" , "something seen as a threat" , "Respect for a ghost" , "Narrow ravine" , "spirit" .)
