Facade even confused queen (6)
I believe the answer is:
veneer
'facade' is the definition.
(I've seen this before)
'even confused queen' is the wordplay.
'confused' indicates anagramming the letters.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'even' is an anagram of 'vene'.
'vene'+'er'='VENEER'
(Other definitions for veneer that I've seen before include "Thin layer on surface, often of furniture" , "Thin wooden surface" , "Prepared" , "Mask; gloss" , "Specious outward appearance of good quality" .)
