Particular honour (7)
I believe the answer is:
respect
I believe this clue is a double definition.
'particular' is the first definition.
(both can mean a detail or matter for consideration)
'honour' is the second definition.
(I know that honour can be written as respect)
(Other definitions for respect that I've seen before include "Treat with care, deference" , "Feeling of deep admiration" , "Show deference (to)" , "Venerate" , "Admiration or esteem" .)
