Essentially silent, if bewildered (2,6)

I believe the answer is:

in itself

'essentially' is the definition.
(I've seen this in another clue)

'silent if bewildered' is the wordplay.
'bewildered' indicates an anagram.
'silent'+'if'='silentif'
'silentif' is an anagram of 'IN ITSELF'.

(Another definition for in itself that I've seen is " essentially".)

I've seen this clue in The Guardian.
