Copy clothing little Parisian is liking (8)
I believe the answer is:
appetite
'is liking' is the definition.
(I've seen this in another clue)
'copy clothing little parisian' is the wordplay.
'copy' becomes 'ape' (ape can mean to copy or imitate).
'clothing' means one lot of letters goes inside another (some letters cover up or clothe others).
'little parisian' becomes 'petit' (I am not sure about this - if you are sure you should believe this answer much more).
'ape' placed around 'petit' is 'APPETITE'.
Can you help me to learn more?
(Other definitions for appetite that I've seen before include "Physical need for food" , "Physical desire as for food" , "Justification for dining" , "demand" , "thirst" .)
