Tease the abstract art lover (8)
I believe the answer is:
aesthete
'art lover' is the definition.
(I've seen this before)
'tease the abstract' is the wordplay.
'abstract' indicates anagramming the letters.
'tease'+'the'='teasethe'
'teasethe' anagrammed gives 'AESTHETE'.
(Other definitions for aesthete that I've seen before include "Someone claiming special knowledge of beauty" , "Someone who claims sensibility for art and nature" , "Person seeing beauty in art" , "Self-styled art lover - the tease (anag)" , "One sensitive to art and beauty" .)
