Cries “Yes!” receiving fifty quid (5)
I believe the answer is:
yells
'cries' is the definition.
('yell' can be a synonym of 'cry')
'yes receiving fifty quid' is the wordplay.
'receiving' is an insertion indicator.
'fifty quid' becomes 'll' (I can't justify this - if you can you should give a lot more credence to this answer).
'yes' placed around 'll' is 'YELLS'.
Can you help me to learn more?
(Other definitions for yells that I've seen before include "Cries out" , "Screams" , "Shouts loudly" .)
