Get straight an argument over privileges (3,2,6)
I believe the answer is:
set to rights
'get straight an' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'argument over privileges' is the wordplay.
'argument' becomes 'setto' (set-to can mean a fight or argument).
'over' is a charade indicator (letters next to each other) (in a down clue, some letters go over others).
'privileges' becomes 'rights' (I've seen this in another clue).
'setto'+'rights'='SET TO RIGHTS'
Can you help me to learn more?
(Other definitions for set to rights that I've seen before include "Put in proper order" , "Restore to the correct state" .)
