Twice stop Scot getting savage (9)
I believe the answer is:
barbarian
'savage' is the definition.
(I know that savage can be written as barbarian)
'twice stop scot getting' is the wordplay.
'twice' indicates the doubling of some letters.
'stop' becomes 'bar' (bar can mean to stop or prevent).
'scot' becomes 'ian' (Scottish given name).
'getting' means one lot of letters go next to another.
'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" .)
