Characteristic courtesy (7)
I believe the answer is:
respect
I believe this is a double definition.
'characteristic' is the first definition.
(thesaurus)
'courtesy' is the second definition.
(I know that respect is a type of courtesy)
(Other definitions for respect that I've seen before include "Appreciate - courtesy" , "Show deference (to)" , "value" , "Spectre (anag.)" , "relation" .)
