vitamin

vitamin: [20] Vitamins were originally vitamines: the Polish-born biochemist Casimir Funk who introduced them to the world in 1920 believed that they were amino acids and so formed the name from Latin vita ‘life’ and amine. It was soon discovered that Funk’s belief was mistaken, and alternative names were suggested, but in 1920 it was successfully proposed (by J.C. Drummond) that the -e be dropped to avoid confusion, and the form vitamin was born.
=> amine, vital

vitamin (n.)

1920, originally vitamine (1912) coined by Polish biochemist Casimir Funk (1884-1967), from Latin vita "life" (see vital) + amine, because they were thought to contain amino acids. The terminal -e formally was stripped off when scientists learned the true nature of the substance; -in was acceptable because it was used for neutral substances of undefined composition. The lettering system of nomenclature (Vitamin A, B, C, etc.) was introduced at the same time (1920).
