stupid (English)

Where does "stupid" come from?

The English adjective 'stupid' traces its lineage back to the Latin adjective 'stupidus', meaning 'struck senseless, amazed', which derived from the verb 'stupeō' meaning 'to be amazed or confounded, be struck senseless'[1]. This Latin term entered English via Middle French 'stupide'[1]. Further back, the Latin root connects to Proto-Indo-European forms such as '*(s)tup-' and '*(s)tewp-', meaning 'to push, stick', which itself extended from the base '*(s)tew-' meaning 'to push, hit'[1][3].
