Put off dance then argue for reparation (10)
I believe the answer is:
discourage
'put off' is the definition.
(I've seen this before)
'dance then argue for reparation' is the wordplay.
'dance' becomes 'disco' (disco can mean a dance event).
'then' means one lot of letters go next to another.
'for reparation' indicates an anagram (I've seen this in other clues).
'argue' anagrammed gives 'urage'.
'disco'+'urage'='DISCOURAGE'
(Other definitions for discourage that I've seen before include "Cause loss of enthusiasm in (someone)" , "Deter; dishearten" , "Put off" , "Talk out of" , "Try to stop" .)
