Putting together catalogue for couple with island shop (9)
I believe the answer is:
itemising
'putting together catalogue' is the definition.
I can't judge whether this defines the answer.
'couple with island shop' is the wordplay.
'couple' becomes 'item' (a romantic couple are 'an item').
'with' is a charade indicator (letters next to each other).
'island shop' becomes 'ising' (I am not sure about this - if you are sure you should believe this answer much more).
'item'+'ising'='ITEMISING'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for itemising that I've seen before include "Listing individually" , "Detailing" .)
