Money's split up on The Chase (7)
I believe the answer is:
hunting
'the chase' is the definition.
(I've seen this before)
'money's split up' is the wordplay.
'money' becomes 'tin' (I've seen this before).
'split' is an insertion indicator.
'up' becomes 'hung' (I can't justify this - if you can you should give a lot more credence to this answer).
'tin' inserted into 'hung' is 'HUNTING'.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for hunting that I've seen before include "Controversial rural pursuit" , "The chase" , "Simple bell-ringing system; chasing" , "Countryside pursuit" , "Tracking down" .)
