nicotine

The term 'nicotine' is a classic example of a word formed through eponymy, deriving from the name of a person. It entered European scientific vocabulary via French, honoring Jean Nicot de Villemain, who sent tobacco seeds and powder to the French court around 1560. The suffix '-ine' is a common chemical suffix in French and English, used to form names of alkaloids and other basic substances (e.g., caffeine, quinine). Thus, the word's journey is not one of combined morphemes with ancient roots, but a modern construction that fossilizes a historical figure's association with the plant, with the chemical compound itself being isolated and named centuries later.

The word is a loanword adopted as a single, unanalyzable unit in English. It originates from the French 'nicotine', which was named after Jean Nicot, the French ambassador to Portugal who promoted the medicinal use of tobacco in the 16th century.
