Lunch is the meal you eat in the middle of the day. If you only have a short lunch break during your school or work day, you might quickly eat a peanut butter and jelly sandwich.

The size of your lunch depends on what country you live in. In the US, most people eat a small lunch and a larger dinner at the end of the day. The word is a somewhat fancy verb, too: "Shall we lunch at the club, or have the cook make us something at home?" Lunch is a shortened version of luncheon, which may stem from the earlier dialectical lunch, "hunk of bread and cheese."
