Beat for some money (5)
I believe the answer is:
pound
I believe this clue is a double definition.
'beat' is the first definition.
(synonyms)
'some money' is the second definition.
(pound sterling)
'for' is the link.
(Other definitions for pound that I've seen before include "Caged poet" , "Enclosure for stray animals" , "Repeatedly strike" , "Lay on, money" , "British currency" .)
