saccharin: [19] Medieval Latin saccharum ‘sugar’ belonged to the same word-family as the ancestor of English sugar. Its original contribution to English was the adjective saccharine ‘sugary’ [17]; and in the late 1870s the German chemist Fahlberg used it in coining the term saccharin for the new sweetening substance he had invented. English borrowed it in the mid 1880s. => sugar[saccharin etymology, saccharin origin, 英语词源]
