supper (n.)

13世纪中期， soper，“一天中的最后一餐”，源自古法语 soper “晚餐”，该词源于日耳曼语（见 sup（v.1））。

Formerly, the last of the three meals of the day (breakfast, dinner, and supper); now applied to the last substantial meal of the day when dinner is taken in the middle of the day, or to a late meal following an early evening dinner. Supper is usually a less formal meal than late dinner. [OED]

曾经是一天中的三餐之一（早餐、午餐和晚餐）的最后一餐； 现在用于在中午吃午餐或在早晚吃晚餐后的晚餐。晚餐通常比晚餐要正式得少。[OED]

自公元1300年以来，用于指耶稣的最后一餐。
