Kind of party in office after charitable event set up (6)
I believe the answer is:
garden
'kind of party' is the definition.
'office after charitable event set up' is the wordplay.
I cannot quite understand how this works, but
'office' could be 'den' (I've seen this before) and 'den' is present in the answer.
The remaining letters 'gar' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'in' is the link.
Can you help me to learn more?
(Other definitions for garden that I've seen before include "Cultivated area" , "Plant growing area" , "Green space attached to a house" , "Danger in Eden?" , "Plot of ground for plants" .)
