Meal is again over (6)
I believe the answer is:
repast
'meal' is the definition.
(I know this)
'again over' is the wordplay.
'again' becomes 're' (prefix meaning 'again').
'over' becomes 'past' (I've seen this in another clue).
're'+'past'='REPAST'
'is' acts as a link.
(Other definitions for repast that I've seen before include "Feast, meal" , "Something to eat" , "lunch?" , "A formal sort of meal" , "Prates about meal" .)
