Party people in charitable activity (8)
I believe the answer is:
donation
'party people in charitable activity' is the definition.
'donation' can be an answer for 'party' (thesaurus). I'm not certain of the 'people in charitable activity' bit.
'party people' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'people' becomes 'nation'.
'do'+'nation'='DONATION'
Can you help me to learn more?
(Other definitions for donation that I've seen before include "An offering or charitable gift" , "present" , "Do anoint by way of a gift" , "Money given to charity" , "Gift or contribution" .)
