Devotee getting record on impulse, oddly (8)
I believe the answer is:
disciple
'devotee' is the definition.
(thesaurus)
'record on impulse oddly' is the wordplay.
'record' becomes 'disc' ('disc' can be a synonym of 'record').
'on' means one lot of letters go next to another.
'oddly' means one should take alternating letters.
The alternating letters of 'impulse' are 'iple'.
'disc'+'iple'='DISCIPLE'
'getting' acts as a link.
(Other definitions for disciple that I've seen before include "Student - follower" , "Personal follower of Christ" , "Follower of a religious leader" , "one believes" , "Devout follower" .)
