Origin
Mid 16th century: from French stupide or Latin stupidus, from stupere 'be amazed or stunned'.
Our word stupid comes from French stupide or Latin stupidus, from stupere ‘to be amazed or stunned’, also the source of stupor (Late Middle English) and stupendous (mid 16th century). The ‘slow-witted, foolish’ sense dates from a similar period and eventually became established as the main meaning.
