Word History

Etymology

alteration of earlier capsicine, capsicin "material extracted from cayenne pepper," borrowed from German Capsicin, from New Latin Capsicum capsicum + German -in -in entry 1

Note: Name introduced by the British physician and chemist John Clough Thresh (1850-1932) in "Capsaicin, the Active Principle of Capsicum Fruits," The Pharmaceutical Journal and Transactions, 3. series, Vol. 7 (July 3, 1876), p. 21. Thresh altered the name more or less arbitrarily, presumably to prevent confusion with the name for the earlier mixture, the impurity of which he demonstrated. German Capsicin appears to have been introduced by the chemist Christian Friedrich Buchhol(t)z in "Chemische Untersuchung der trockenen reifen spanischen Pfeffers," Almanach oder Taschenbuch für Scheidekünstler und Apotheker, vol. 37 (1816), pp. 1-30.
