Come to ace funeral party (5)
I believe the answer is:
awake
'come to' is the definition.
(I've seen this in another clue)
'ace funeral party' is the wordplay.
'ace' becomes 'a'.
'funeral party' becomes 'wake' (I've seen this before).
'a'+'wake'='AWAKE'
(Other definitions for awake that I've seen before include "Come to" , "Alive and alert" , "Conscious, aware" , "On the ball?" , "Make active again" .)
