Permit creativity (7)
I believe the answer is:
licence
This clue is a double definition.
'permit' is the first definition.
(I've seen this before)
'creativity' is the second definition.
(as in artistic licence)
(Other definitions for licence that I've seen before include "Formal permit" , "A writer's exaggeration" , "Permit - excessive behaviour" , "Pass" , "Legal document giving official permission" .)
