Type of all-male party: people in an unwholesome state (10)
I believe the answer is:
stagnation
'an unwholesome state' is the definition.
'stagnation' can be an answer for 'state' (stagnation is a kind of state). I'm not sure about the 'an unwholesome' bit.
'type of all-male party people' is the wordplay.
'type of all male party' becomes 'stag' (I can't justify this - if you can you should give a lot more credence to this answer).
'people' becomes 'nation'.
'stag'+'nation'='STAGNATION'
'in' is the link.
Can you help me to learn more?
(Other definitions for stagnation that I've seen before include "Lack of activity" , "sluggish" , "State of little activity" , "Lack of movement or growth" , "State of lethargy" .)
