Abandon report in course (7)
I believe the answer is:
dessert
'course' is the definition.
(dessert is a kind of course)
'abandon report' is the wordplay.
'abandon' becomes 'desert' (desert can mean to leave or abandon).
'report' indicates a 'sounds like' (homophone) clue (as heard, or reported by someone).
'desert' is a homophone of 'DESSERT'.
'in' acts as a link.
(Other definitions for dessert that I've seen before include "Christmas pudding maybe" , "Sweet, last course of a meal" , "Fool possibly" , "Fruit and nuts, perhaps" , "tart?" .)
