Burn a label (5)
I believe the answer is:
brand
I believe this is a double definition.
'burn' is the first definition.
(thesaurus)
'a label' is the second definition.
('brand' can be a synonym of 'label')
(Other definitions for brand that I've seen before include "Comedian" , "Stamp" , "Make of product" , "Norwegian play" , "Tradename" .)
