Given good spirit, but aim to drink beer (10)
I believe the answer is:
encouraged
'given good spirit' is the definition.
(encouragement raises one's spirits)
'aim to drink beer' is the wordplay.
'aim' becomes 'end' (both can mean a goal or purpose).
'to drink' indicates putting letters inside.
'beer' becomes 'courage' (beer is 'liquid courage').
'end' going around 'courage' is 'ENCOURAGED'.
'but' is the link.
(Other definitions for encouraged that I've seen before include "Inspired with confidence" , "Heartened" , "helped" , "Urged" .)
