Finicky item (10)
I believe the answer is:
particular
I believe this is a double definition.
'finicky' is the first definition.
(I know that finicky can be written as particular)
'item' is the second definition.
(I know that item can be written as particular)
(Other definitions for particular that I've seen before include "Fog over London" , "certain" , "Specific" , "Nice" , "Respect" .)
