Temporarily stop suer not taking 50% pay-out (7)
I believe the answer is:
suspend
'temporarily stop' is the definition.
(suspend can mean to stop for a period of time)
'taking 50% pay-out' is the wordplay.
'taking' is an insertion indicator.
'50%' becomes 'us' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'pay-out' becomes 'spend'.
'us' going inside 'spend' is 'SUSPEND'.
'suer not' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for suspend that I've seen before include "Put in abeyance" , "Fail to hit" , "Remove temporarily from office - hang" , "Temporarily halt; hang" , "Stop for a time" .)
