Award most of money before rift (6)
I believe the answer is:
breach
'rift' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for breach that I've seen before include "transgression" , "The breaking of a law or agreement" , "Violation, maybe of the peace" , "Split, break" , "Break, an agreement say" .)
