Repeatedly stop Scot being a savage (9)
I believe the answer is:
barbarian
'a savage' is the definition.
(I know that savage can be written as barbarian)
'repeatedly stop scot' is the wordplay.
'repeatedly' says to double the letters.
'stop' becomes 'bar' (bar can mean to stop or prevent).
'scot' becomes 'ian' (Scottish given name).
'bar' doubled is 'barbar'.
'barbar'+'ian'='BARBARIAN'
'being' is the link.
(Other definitions for barbarian that I've seen before include "Uncivilised - Goth" , "An uncivilised, rough person" , "Brutish type" , "outlandish foreigner" , "Savage - rugby player" .)
