1911 Encyclopædia Britannica/Dinner
DINNER, the chief meal of the day, eaten either in the middle of the day, as was formerly the universal custom, or in the evening. The word “dine” comes through Fr. from Med. Lat. disnare, for disjejunare, to break one’s fast (jejunium); it is, therefore, the same word as Fr. déjeuner, to breakfast, in modern France, to take the midday meal, dîner being used for the later repast. The term “dinner-wagon,” originally a movable table to hold dishes, is now used of a two-tier sideboard.
