Sculpture, perhaps, of Trump grabbing popular chanteuse's backside (4,3)
I believe the answer is:
fine art
'sculpture perhaps' is the definition.
(sculpture is a kind of fine art)
'trump grabbing popular chanteuse's backside' is the wordplay.
I cannot really understand how this works, but
'popular' could be 'in' ('in' can mean trendy) and 'in' is found in the answer.
The remaining letters 'feart' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for fine art that I've seen before include "Such as painting, sculpture or architecture" , "Thing of beauty" , "Canvas perhaps" , "In after (anag) - painting, sculpture etc" , "aesthetic production" .)
