Be reconciled, after brush with assembly (4,3,4,2)
I believe the answer is:
kiss and make up
'be reconciled' is the definition.
(I've seen this before)
'after brush with assembly' is the wordplay.
'after' is a charade indicator (letters next to each other).
'brush' becomes 'kiss' (synonyms).
'with' becomes 'and'.
'assembly' becomes 'makeup' (I can't explain this - if you can you should believe this answer much more).
'kiss' put next to 'and' is 'kissand'.
'kissand'+'makeup'='KISS-AND-MAKE-UP'
Can you help me to learn more?
(Other definitions for kiss and make up that I've seen before include "Forgive and forget" , "reconcile differences" , "Become reconciled" .)
