Chanel, say, fanatic for tropical fruit (7)
I believe the answer is:
coconut
'tropical fruit' is the definition.
'chanel say fanatic' is the wordplay.
I cannot really see how this works, but
'chanel' could be 'coco' (I've seen this in another clue) and 'coco' is found within the answer.
'fanatic' could be 'nut' (I've seen this in another clue) and 'nut' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for coconut that I've seen before include "Shy occupier" , "Large edible fruit" , "Oval nut with fibrous husk" , "fair target" , "one of a lovely bunch?" .)
