v. eat an afternoon meal; eat a light meal, have a snack; host guests for an afternoon meal

n. afternoon meal; light meal, snack

Lunch is an abbreviation of luncheon, meaning a midday meal. In English-speaking countries during the eighteenth century what was originally called "dinner"— a word still sometimes used to mean a noontime meal in the  British Isles, and in parts of the United States and Canada — was moved by stages later in the day and came in the course of the nineteenth century to be eaten at night, replacing the light meal called  supper, which was delayed by the upper class to midnight.
