Dinner or lunch (4)
I believe the answer is:
meal
I believe this is a double definition.
'dinner' is the first definition.
(dinner is a meal)
'lunch' is the second definition.
(I've seen this in another clue)
(Other definitions for meal that I've seen before include "Lunch or dinner, say" , "Eg, dinner or tea" , "Lame (anag.)" , "Supper, e.g." , "Food ground up" .)
