Gift party to the country (8)
I believe the answer is:
donation
'gift' is the definition.
(I know that donation is a type of gift)
'party to the country' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'to the country' becomes 'nation' ('nation' can be a synonym of 'country').
'do'+'nation'='DONATION'
(Other definitions for donation that I've seen before include "present" , "presentation" , "An offering or charitable gift" , "Gift of money as to charity" , "Money given to charity" .)
