Regard spectre another way (7)
I believe the answer is:
respect
'regard' is the definition.
(I know that respect is a more specific form of regard)
'spectre another way' is the wordplay.
'another way' indicates anagramming the letters.
'spectre' with letters rearranged gives 'RESPECT'.
(Other definitions for respect that I've seen before include "Scrupulously heed" , "Admiration or esteem" , "to abide by" , "Regard and treat well" , "Due regard; detail" .)
