Cruelly tease the art lover (8)
I believe the answer is:
aesthete
'art lover' is the definition.
(I've seen this before)
'cruelly tease the' is the wordplay.
'cruelly' indicates anagramming the letters (I've seen this in other clues).
'tease'+'the'='teasethe'
'teasethe' anagrammed gives 'AESTHETE'.
(Other definitions for aesthete that I've seen before include "person of culture" , "Person with great sensitivity towards the arts and the beautiful" , "Person with great appreciation of the beautiful" , "One affecting great love of the arts - the tease (anag)" , "Estate he settled on lover of beautiful things" .)
