Dunch refers to a meal enjoyed subsequent to lunch but prior to dinner, just like "brunch" is typically the meal between breakfast and lunch.

Dunch指在午餐之后、晚餐之前吃的饭，跟早餐和午餐之间的早午餐（brunch）类似。

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.

不过，dunch要跟linner区分开来。二者均表示在午餐之后、晚餐之前吃的饭，不过，dunch的时间要比linner靠后，离晚餐时段更近一些。

Thus, the socially accepted norm with regard to afternoon eating agendas comprises the following progression of meals: Lunch --> Linner --> Dunch --> Dinner.

由此，社交场合中在下午进行的各类进餐次序应该是这样的：午餐（lunch）-->晚午餐（linner）-->午晚餐（dunch）-->晚餐（dinner）。
