Part of the meal lacking refinement reportedly (6)
I believe the answer is:
course
'part of the meal' is the definition.
('course' is part of 'meal')
'lacking refinement reportedly' is the wordplay.
'lacking refinement' becomes 'coarse' (I've seen this before).
'reportedly' indicates a 'sounds like' (homophone) clue.
'coarse' is a homophone of 'COURSE'.
(Other definitions for course that I've seen before include "Pursue - career - run - series of lectures" , "Path of a river or a set of lessons" , "Prescribed number of lessons" , "Curriculum" , "Path along which something moves" .)
