One can spin in fruit machine (9)
I believe the answer is:
appliance
'machine' is the definition.
(I've seen this before)
'one can spin in fruit' is the wordplay.
'one' becomes 'I' (Roman numeral).
'spin' indicates anagramming the letters.
'in' indicates putting letters inside.
'fruit' becomes 'apple' (apple is a kind of fruit).
'i'+'can'='ican'
'ican' anagrammed gives 'ianc'.
'ianc' placed inside 'apple' is 'APPLIANCE'.
(Other definitions for appliance that I've seen before include "Tool or device for a specific task" , "Machine, piece of equipment" , "implement" , "Washing machine or toaster, say" , "food mixer, perhaps" .)
