Pass Asian currency to the senior person (5)
I believe the answer is:
doyen
'the senior person' is the definition.
(I've seen this before)
'pass asian currency' is the wordplay.
'pass' becomes 'do' (doing is a kind of passing).
'asian currency' becomes 'yen' (I've seen this in another clue).
'do'+'yen'='DOYEN'
'to' is the link.
(Other definitions for doyen that I've seen before include "Most valued prof, eg" , "Most prominent expert" , "Senior person" , "Grand old man" , "Senior man of a group" .)
