Tradename or trademark (5)
I believe the answer is:
brand
I believe this clue is a double definition.
'tradename' is the first definition.
(I've seen this before)
'trademark' is the second definition.
(I've seen this before)
(Other definitions for brand that I've seen before include "Type - it's burning" , "Stamp" , "a particular kind" , "Type of product; sword" , "Ibsen play; trade name" .)
