And put on the primer badly, getting a rebuke (9)
I believe the answer is:
reprimand
'a rebuke' is the definition.
('reprimand' can be a synonym of 'rebuke')
'and put on the primer badly' is the wordplay.
'put on' means one lot of letters go next to another.
'badly' is an anagram indicator.
'primer' is an anagram of 'reprim'.
'and' after 'reprim' is 'REPRIMAND'.
'getting' acts as a link.
(Other definitions for reprimand that I've seen before include "Severe reproof" , "Formal rebuke" , "Tick off - carpet" , "Expression of disapproval" , "Severe telling-off" .)
