Origin of Drug

  • From Middle English drogge (“medicine”), from Middle French drogue (“cure, pharmaceutical product”), from Old French drogue, drocque (“tincture, pharmaceutical product”), from Middle Dutch or Middle Low German droge, as in droge vate (“dry vats, dry barrels”), mistaking droge for the contents, which were wontedly dried herbs, plants or wares. Droge comes from Middle Dutch drōghe (“dry”), from Old Dutch drōgi (“dry”), from Proto-Germanic *draugiz (“dry, hard”). Cognate with English dry, Dutch droog (“dry”), German trocken (“dry”).
