Aide during break delivering meal (6)
I believe the answer is:
repast
'meal' is the definition.
(repast can mean a meal)
'aide during break' is the wordplay.
'aide' becomes 'pa' (abbreviation for personal assistant).
'during' is an insertion indicator.
'break' becomes 'rest' (a rest is taking a break).
'pa' put into 'rest' is 'REPAST'.
'delivering' is the link.
(Other definitions for repast that I've seen before include "A meal concerning time gone by" , "Something to eat" , "Prates about meal" , "A formal sort of meal" , "lunch?" .)
