Fussy point (10)
I believe the answer is:
particular
I believe this is a double definition.
'fussy' is the first definition.
(I know that fussy can be written as particular)
'point' is the second definition.
(particular can mean a point or detail)
(Other definitions for particular that I've seen before include "Meticulous" , "Respect" , "Special" , "Specific" , "certain" .)
