A particular deference (7)
I believe the answer is:
respect
I believe this is a double definition.
'a particular' is the first definition.
(both can mean a detail or matter for consideration)
'deference' is the second definition.
(I know that deference can be written as respect)
(Other definitions for respect that I've seen before include "Reverence" , "Refuse to offend" , "Avoid offending" , "estimation" , "Pay attention to" .)
