Place on one side? Correct (3,5)
I believe the answer is:
put right
'correct' is the definition.
(thesaurus)
'place on one side?' is the wordplay.
'place' becomes 'put' ('put' can be a synonym of 'place'**).
'on' is a charade indicator (letters next to each other).
'one side?' becomes 'right'.
'put'+'right'='PUT RIGHT'
(Other definitions for put right that I've seen before include "Repair" , "Correct" , "Make good" .)
