Etymology: Sinapine is a chemical compound, and its name points straight back to the mustard plant. The Latin "sinapi" and "sinapis" both meant "mustard," borrowed from Ancient Greek, and the word reached English through French, where "sinapine" was already in use. The suffix "-ine" is the standard chemistry ending used for alkaloids and other nitrogen-containing compounds derived from plants. The name fits the source: sinapine is found in mustard seeds, where it is one of the substances that gives mustard its character. Chemists named it after the genus that yields it, so the word carries the plant's name into the laboratory.
