Tease the silly art lover (8)
I believe the answer is:
aesthete
'art lover' is the definition.
(I've seen this in another clue)
'tease the silly' is the wordplay.
'silly' is an anagram indicator.
'tease'+'the'='teasethe'
'teasethe' with letters rearranged gives 'AESTHETE'.
(Other definitions for aesthete that I've seen before include "person of culture" , "Arts lover" , "Person seeing beauty in art" , "Someone claiming special knowledge of beauty" , "One sensitive to art and beauty" .)
