vitamin
UK: ˈvɪtəmɪn | US: ˈvaɪtəmɪn
n. any of a group of organic compounds essential in small quantities for normal metabolism and health
The word "vitamin" was coined in 1912 by Polish biochemist Casimir Funk. He derived it from the Latin "vita" (life) and "amine" (a type of nitrogen-containing compound), as he initially believed all vitamins were amines. Though later discoveries proved this incorrect, the term stuck with a slight spelling change ("amine" → "amin"). The morpheme "vita" reflects the life-sustaining role of these nutrients, while "min" evolved as a general suffix for biochemical substances.
