Contract for sporting prize (5)
I believe the answer is:
purse
This clue might be a double definition.
'contract' is the first definition.
(as in pursing one's lips)
'sporting prize' is the second definition.
'purse' can be an answer for 'prize' (I've seen this before). I am not sure about the 'sporting' bit.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for purse that I've seen before include "Prize money - prepare to whistle" , "sometimes with strings attached?" , "Contract orally" , "Winner's prize" , "Pucker (one's lips)" .)
