Courteous regard (9)
I believe the answer is:
deference
'courteous regard' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for deference that I've seen before include "Respect; submission" , "honour" , "Compliance with another's wishes, polite respect" , "Reed fence? (anag)" , "Submission to will of another" .)
