English Etymology vitamin 1920, originally vitamine (1912) coined by Pol. biochemist Casimir Funk (1884-1967), from L. 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. Oxford Collocations Dictionary for Students of English vitamin ADJ. take The doctor told me to take vitamins regularly. VERB + VITAMIN contain Most foods contain vitamin E. | be rich in Fish is rich in vitamins and minerals. | enrich sth with, fortify sth with breakfast cereals enriched with vitamins VITAMIN + NOUN drops, injections, pills, supplements, tablets | requirements | deficiency Vitamin C deficiency can ultimately lead to scurvy.
