Party longing for most respected member (5)
I believe the answer is:
doyen
'respected member' is the definition.
(I've seen this in another clue)
'party longing' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'longing' becomes 'yen' (yen can mean a desire or longing for something).
'do'+'yen'='DOYEN'
'for most' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for doyen that I've seen before include "Senior member of a profession or academy" , "Dean of an academy" , "Most valued prof, eg" , "Respected senior member" , "As senior statesman" .)
