Regard spectre suspiciously (7)
I believe the answer is:
respect
'regard' is the definition.
(I know that regard can be written as respect)
'spectre suspiciously' is the wordplay.
'suspiciously' is an anagram indicator (I've seen this in other clues).
'spectre' is an anagram of 'RESPECT'.
(Other definitions for respect that I've seen before include "Have high regard for sceptre" , "Appreciation" , "High opinion or regard for" , "Sceptre (anag)" , "Hold in high regard" .)
