Brunch or dinner (4)
I believe the answer is:
meal
This clue is a double definition.
'brunch' is the first definition.
(I've seen this in another clue)
'dinner' is the second definition.
(dinner is a meal)
(Other definitions for meal that I've seen before include "Lame (anag.)" , "Flour; food" , "Grain ground to powder" , "Eg, dinner or tea" , "Ground grain or pulses" .)
