Twice stop Scot getting savage (9)
I believe the answer is:
barbarian
'savage' is the definition.
('barbarian' can be a synonym of 'savage')
'twice stop scot getting' is the wordplay.
'twice' says to double the letters.
'stop' becomes 'bar' (I've seen this before).
'scot' becomes 'ian'.
'getting' is a charade indicator (letters next to each other).
'bar' duplicated is 'barbar'.
'barbar'+'ian'='BARBARIAN'
(Other definitions for barbarian that I've seen before include "wild fellow" , "Brutish type" , "Uncultured, brutish" , "Crude" , "uncivilised man" .)
