One remarkably animated in party, given drink (7)
I believe the answer is:
galatea
'one remarkably animated' is the definition.
(statue brought to life in Greek myth)
'party given drink' is the wordplay.
'party' becomes 'gala' (I've seen this before).
'given' is a charade indicator (letters next to each other).
'drink' becomes 'tea' (tea is a kind of drink).
'gala'+'tea'='GALATEA'
'in' acts as a link.
(Other definitions for galatea that I've seen before include "Pygmalion's statue that lived" , "Pygmalion's brought-to-life statue" , "Pygmalion's statue brought to life by Aphrodite" .)
