Model basically embracing rejection of fur (5)
I believe the answer is:
sable
'fur' is the definition.
(I know that sable is a type of fur)
'model basically embracing rejection' is the wordplay.
'embracing' indicates the answer is hidden within the clue (the solution is embraced by words in the clue).
'rejection' says the letters should be written backwards (to reject is to send back).
'elbas' is hidden within 'model basically'.
'elbas' backwards is 'SABLE'.
'of' acts as a link.
(Other definitions for sable that I've seen before include "Antelope, fur" , "Type of fur" , "Adventurous courage" , "Bales of precious fur" , "Dark brown fur of the marten" .)
