A baker’s dozen is a term used to describe a group of 13 items. The term is often used in the context of baking, where a baker’s dozen refers to 13 loaves of bread or rolls.
The origin of the term “baker’s dozen” is not entirely clear, but it is thought to have originated in medieval England. At the time, bakers were required to sell their goods by weight, and to ensure that they did not shortchange their customers, they often included an extra loaf of bread or roll in a dozen. This extra loaf or roll was known as the “baker’s dozen,” and the practice of including it became a common way for bakers to show their customers that they were being honest and fair in their business dealings.
Today, the term “baker’s dozen” is used more generally to refer to any group of 13 items, and is not necessarily limited to the context of baking. It is often used as a way to describe a group of items that is slightly larger than the usual number, or as a way to indicate that something is being offered in a larger quantity than usual.
