1.
noun.

Dunch refers to a meal enjoyed subsequent to lunch but prior to dinner.

Dunch should be distinguished from linner, another meal occurring in the post-lunch, pre-dinner interval, in that dunch occurs after linner, closer to dinner time.

Thus, the socially accepted norm with regard to afternoon eating agendas comprises the following progression of meals:

Lunch --> Linner --> Dunch --> Dinner
