Dropping off a sack full of money (7)
I believe the answer is:
abating
'dropping' is the definition.
The answer and definition can be both related to change as well as being present participle verbs.
Maybe they are linked in a way I don't understand?
'a sack full of money' is the wordplay.
'sack' becomes 'bag' (I've seen this before).
'full of' indicates putting letters inside.
'money' becomes 'tin' (old-fashioned slang term for money).
'bag' placed around 'tin' is 'bating'.
'a'+'bating'='ABATING'
'off' acts as a link.
Can you help me to learn more?
(Other definitions for abating that I've seen before include "Slacking off, dyeing away" , "Dying away, slacking off" , "Getting less" , "Subsiding" , "Becoming less intense" .)
