Pose maybe for money (4)
I believe the answer is:
peso
'money' is the definition.
(I have seen 'Mexican money ' mean 'peso' so perhaps 'money' could also mean 'peso')
'pose maybe' is the wordplay.
'maybe' indicates anagramming the letters.
'pose' with letters rearranged gives 'PESO'.
'for' is the link.
(Other definitions for peso that I've seen before include "Mexican monetary unit" , "Mexican dollar" , "Currency of Mexico" , "Foreign currency" , "Mexican coin" .)
