Senior member makes the same money (5)
I believe the answer is:
doyen
'senior member' is the definition.
(I've seen this before)
'the same money' is the wordplay.
'the same' becomes 'do' (abbreviation for ditto).
'money' becomes 'yen' (Japanese currency).
'do'+'yen'='DOYEN'
'makes' is the link.
(Other definitions for doyen that I've seen before include "Senior male figure in a profession" , "Senior practitioner" , "Senior member of a professional group" , "The most respected among experts" , "As senior statesman" .)
