Breakfast is the first meal taken after rising from a night's sleep, most often eaten in the early morning before undertaking the day's work. The Old English word for dinner, disner, means to break a fast, and was the first meal eaten in the day until its meaning shifted in the mid-13th century. It was not until the 15th century that “breakfast” came into use in written English to describe a morning meal, which literally means to break the fasting period of the prior night; in Old English the term was morgenmete meaning "morning meal."
