Stole material from Corfu retailer (3)
I believe the answer is:
fur
'stole material' is the definition.
(I've seen this in another clue)
'from corfu retailer' is the wordplay.
'from' indicates a hidden word.
'FUR' can be found hidden inside 'corfu retailer'.
(Other definitions for fur that I've seen before include "Animal skin like mink or sable" , "Hairy animal's coat" , "Coating formed on sick person's tongue (3)" , "Hide" , "Outer skin of animal with hair attached" .)
