The word "glycerin" is derived from the Greek word "glykys", meaning "sweet", and the suffix "-erine", commonly used in the names of chemical compounds. The term was coined by the French chemist Michel Eugène Chevreul in the early 19th century, who discovered that by hydrolyzing (breaking down by water) animal fats, a sweet-tasting substance could be obtained, which he named "glycérine". Over time, the spelling evolved to "glycerin" and became widely used in English.
