Some are licensed to provide a souvenir (5)
I believe the answer is:
relic
'a souvenir' is the definition.
(I know that souvenir can be written as relic)
'some are licensed to' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'RELIC' is hidden in the letters of 'are licensed to'.
'provide' is the link.
(Other definitions for relic that I've seen before include "Long-surviving object" , "Revered object" , "Memorial of antiquity" , "Ancient and venerated object" , "Object of reverence" .)
