Scorn erroneously about angle (6)
I believe the answer is:
corner
'angle' is the definition.
(thesaurus)
'scorn erroneously about' is the wordplay.
'about' indicates the answer is hidden within the clue.
'CORNER' is hidden in the letters of 'scorn erroneously'.
(Other definitions for corner that I've seen before include "Angular projection" , "Place where two streets meet" , "Bend" , "Difficult position; angle" , "Monopolise" .)
