Savage ban is repeatedly put on Scotsman (9)
I believe the answer is:
barbarian
'savage' is the definition.
('barbarian' can be a synonym of 'savage')
'ban is repeatedly put on scotsman' is the wordplay.
'ban' becomes 'bar' (I've seen this before).
'is repeatedly' says to double the letters.
'put on' means one lot of letters go next to another.
'scotsman' becomes 'ian'.
'bar' duplicated is 'barbar'.
'barbar'+'ian'='BARBARIAN'
(Other definitions for barbarian that I've seen before include "outlandish foreigner" , "Crude" , "Uncultured, brutish" , "An uncivilised, rough person" , "uncivilised man" .)
