Raccoon-like mammal’s trimmed fur (4)
I believe the answer is:
coat
'fur' is the definition.
(an animal's coat)
'raccoon-like mammal's trimmed' is the wordplay.
'raccoon-like' becomes 'co' (I can't justify this - if you can you should believe this answer much more).
'mammal's' becomes 'rat's' (rat is a kind of mammal).
'trimmed' says to take the centre (the external letters are trimmed from the word).
The centre of 'rats' is 'at'.
'co'+'at'='COAT'
Can you help me to learn more?
(Other definitions for coat that I've seen before include "Layer of paint" , "Jacket" , "Overgarment" , "Outer garment" , "Ulster, perhaps" .)
