What does gelatin mean?
Gelatin is a translucent, jellylike substance made from collagen found in animal bones, hides, and connective tissue. When dissolved in hot water and cooled, it forms a firm gel, making it an important setting agent for fruit desserts, Aspics, confectionery, and other foods. It also has specialized uses: clear gelatin sheets support photographic emulsions, and pharmaceutical gelatin is used to manufacture capsules. Although everyday food gelatin often appears to be sweet or decorative, the substance itself is neutral and can also serve technical, medical, or industrial purposes. Its familiar wobbling texture makes it instantly recognizable, but its connection to collagen gives it an important structural role in both animal tissues and many manufactured products. The word also reflects its history, since it derives from a Latin term associated with freezing or congealing.

Gelatin's name points to cold: its Latin ancestor means “to freeze” or “congeal.”

Where does gelatin come from?
Gelatin entered English in the early nineteenth century from French gélatine. French borrowed it from Latin gelātīna, which was formed from gelāre, “to freeze” or “to congeal.” The same Latin root underlies English words such as gel, jelly, congeal, and gelid.
