Breakfast or dinner, eg (4)
I believe the answer is:
meal
I believe this is a double definition.
'breakfast' is the first definition.
(thesaurus)
'dinner eg' is the second definition.
(I know that dinner is a type of meal)
(Other definitions for meal that I've seen before include "Food ground up" , "Meat and two veg plus dessert, perhaps" , "Breakfast, dinner or tea" , "Lame (anag.)" , "Food for male" .)
