Definition of jam

The word "jam" has a long and evolving history. The term "jam" originated in the 1520s from the Latin phrase "diasema," meaning "a setting" or "a preserving." This referred to the process of preserving fruit in sugar syrup, which was a common method of food preservation during the Middle Ages. In the 16th century, the term "jam" began to be used in English to describe a sweet spread made from fruit, sugar, and sometimes spices. The word gained popularity in the 17th and 18th centuries as trade and exploration brought new fruits and preservation techniques to Europe. Over time, the meaning of "jam" expanded to include other sweet spreads, such as marmalade and preserves. Today, the term "jam" is used globally to describe a wide range of sweet and savory spreads made from fruit, vegetables, and other ingredients.
