Admire spectre, in a way (7)
I believe the answer is:
respect
'admire' is the definition.
(admire can mean to respect)
'spectre in a way' is the wordplay.
'in a way' is an anagram indicator.
'spectre' is an anagram of 'RESPECT'.
(Other definitions for respect that I've seen before include "Admiration felt for another's good qualities" , "Venerate" , "'Regard, esteem (7)'" , "Deference, obedience" , "High opinion or regard for" .)
