Organised men's party with Edmund (6)
I believe the answer is:
staged
'organised men's' is the definition.
Although both the answer and definition are past participle verbs, I cannot see how one could define the other.
'party with edmund' is the wordplay.
'party' becomes 'stag party' (stag party is a kind of party).
'with' is a charade indicator (letters next to each other).
'edmund' becomes 'ed'.
'stag'+'ed'='STAGED'
Can you help me to learn more?
(Other definitions for staged that I've seen before include "Put on as theatre would" , "(Of play/opera) mounted" , "Get ads (anag) - performed" , "Put on play or other performance" , "Put on (as show)" .)
