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' is an anagram indicator.
'pose' with letters rearranged gives 'PESO'.
'for' acts as a link.
(Other definitions for peso that I've seen before include "Mexican monetary unit" , "Mexican dollar" , "Currency of Mexico" , "Foreign currency" , "Mexican coin" .)
