Give the rest time for a bust-up! (8)
I believe the answer is:
breakage
'a bust-up' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'give the rest time' is the wordplay.
'give' is a charade indicator (letters next to each other).
'the rest' becomes 'break' (I've seen this before).
'time' becomes 'age' (an age is a period of time).
'break' put next to 'age' is 'BREAKAGE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for breakage that I've seen before include "Act of smashing" , "Act of shattering" , "Reimbursement for goods damaged in transit" , "Damage caused by smashing" , "Smashed article" .)
