This word evolved into "luncheon" in Middle English, which initially referred to a small piece of bread or meat eaten as a snack. Over time, "luncheon" became a more general term for a light meal, especially one eaten in the middle of the day.
Eventually, "lunch" emerged as a shorter and simpler form of "luncheon", becoming the word we use today.
So, the next time you enjoy your midday meal, remember that it has roots in a simple, hearty piece of food!
