Luncheon, commonly abbreviated to lunch, is a middle of the day meal, and is generally smaller than dinner, which is the main meal of the day whenever dinner is eaten. The origin of the words lunch and luncheon relate to a small meal originally eaten at any time of the day or night, but during the 20th century gradually focused toward a small meal eaten at midday.
