Surface even confused queen (6)
I believe the answer is:
veneer
'surface' is the definition.
(thesaurus)
'even confused queen' is the wordplay.
'confused' indicates an anagram.
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'even' with letters rearranged gives 'vene'.
'vene'+'er'='VENEER'
(Other definitions for veneer that I've seen before include "Finish" , "Decorative coating" , "A thin outer layer" , "Superficial polish" , "Prepared" .)
