Expert gets money after party (5)
I believe the answer is:
doyen
'expert' is the definition.
(I have seen 'Respected expert ' mean 'doyen' so perhaps 'expert' could also mean 'doyen')
'money after party' is the wordplay.
'money' becomes 'yen' (Japanese currency).
'after' says to put letters next to each other.
'party' becomes 'do' (do is a kind of party).
'yen' after 'do' is 'DOYEN'.
'gets' is the link.
(Other definitions for doyen that I've seen before include "Respected expert" , "Senior practitioner" , "Dean of an academy" , "Top expert in a field" , "Senior male figure in a profession" .)
