Choosy, wanting item (10)
I believe the answer is:
particular
I believe this is a double definition.
'choosy' is the first definition.
(synonyms)
'item' is the second definition.
(I know that item can be written as particular)
'wanting' acts as a link.
(Other definitions for particular that I've seen before include "going into detail" , "item" , "Fastidious; individual" , "Fog over London" , "Exceptional" .)
