Preserve body part nursed by sick Parisian (9)
I believe the answer is:
marmalade
'preserve' is the definition.
(I know that marmalade is a type of preserve)
'body part nursed by sick parisian' is the wordplay.
I cannot quite see how this works, but
'part' could be 'arm' (arm is a kind of part) and 'arm' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for marmalade that I've seen before include "group?" , "Preserve made with citrus fruits" , "Spread" , "Orange conserve" , "Sweet food" .)
