What's the point of feasting? (4)
I believe the answer is:
east
'what's the point' is the definition.
(east is a kind of point)
'of feasting?' is the wordplay.
'of' indicates the answer is hidden within the clue.
'EAST' is hidden within 'feasting'.
(Other definitions for east that I've seen before include "course" , "Tom's schoolfellow" , "major point" , "Oriental lands" , "Where the sun rises" .)
