Come to a funeral party (5)
I believe the answer is:
awake
'come to' is the definition.
(I've seen this before)
'a funeral party' is the wordplay.
'funeral party' becomes 'wake' (I've seen this before).
'a'+'wake'='AWAKE'
(Other definitions for awake that I've seen before include "Rouse; vigilant" , "Stop sleeping" , "Patriotic song 'The West's .....'" , "Become active again" , "No longer in the land of Nod" .)
