Permit silence to be shattered (7)

I believe the answer is:

license

'permit' is the definition.
(I know that permit can be written as license)

'silence to be shattered' is the wordplay.
'to be shattered' indicates anagramming the letters.
'silence' is an anagram of 'LICENSE'.

(Other definitions for license that I've seen before include "Silence about permission to sell" , "Grant formal permission (to)" , "Authorise to sell in silence" , "Silence (anag.)" , "Authorise officially" .)

I've seen this clue in The Telegraph.
