Supper, which is also known as dinner, is usually the third daily meal you eat. Many families try to sit down and eat supper together at the end of the day.
First comes breakfast, then lunch, and then finally, in the evening, it's time for supper. The word supper is less common today than dinner, although North Americans generally consider the words to be synonyms. Until the early 20th century, the meal we now generally refer to as lunch was called dinner, while the evening meal was supper. It comes from the Old French soper, "to eat the evening meal."
