Straightening out urchin's jacket, speaking with menace (10)

Ross

I believe the answer is:

unsnarling

'straightening out' is the definition.
('unsnarl' can be a synonym of 'straighten out')

'urchin's jacket speaking with menace' is the wordplay.
'jacket' says to hollow out the word (remove centre letters) (the letters worn by the word as a 'jacket' are use).
'speaking with menace' becomes 'snarling' (to snarl is to speak in a menacing way).
'urchin' with its centre taken out is 'un'.
'un'+'snarling'='UNSNARLING'

I've seen this clue in The Guardian.
