Work of art superior in taste, maybe (6)
I believe the answer is:
statue
'work of art' is the definition.
(I've seen this in another clue)
'superior in taste maybe' is the wordplay.
'superior' becomes 'U' (U can mean upper-class, as in U and non-U speech).
'in' means one lot of letters goes inside another.
'maybe' is an anagram indicator.
'taste' anagrammed gives 'state'.
'u' put inside 'state' is 'STATUE'.
(Other definitions for statue that I've seen before include "Solid representation of the human form" , "Artistic work" , "Three-dimensional representation" , "Model figure" , "Artistic figure" .)
