"containing tin," 1790, from Modern Latin stannum, from Late Latin stannum "tin" (earlier "alloy of silver and lead"), a scribal alteration of Latin stagnum, probably from a Celtic source (compare Irish stan "tin," Cornish and Breton sten, Welsh ystaen). The Latin word is the source of Italian stagno, French étain, Spanish estaño "tin."
