A filling meal after essentially free promotional event (8)
I believe the answer is:
relaunch
'a filling meal after essentially free promotional event' is the definition.
I can't judge whether this defines the answer.
'after essentially free promotional event' is the wordplay.
'after' is a charade indicator (letters next to each other).
'essentially' indicates the central letters.
'promotional event' becomes 'launch' (eg a product launch).
The middle letters of 'free' are 're'.
're' put next to 'launch' is 'RELAUNCH'.
Can you help me to learn more?
(Other definitions for relaunch that I've seen before include "marketing operation" , "Begin (enterprise) again" , "Again introduce" , "New introduction of old product" .)
