psychomotor (English)

Where does "psychomotor" come from?

The English adjective 'psychomotor' is a modern compound formed from the elements 'psycho-' and 'motor'[1]. The first element 'psycho-' derives from English clippings like 'psychotic'[2]. The second element 'motor' traces back through Middle English 'motour' meaning 'controller, prime mover'[3], which comes from the Latin noun 'mōtor' meaning 'mover'[3], built from the verb 'moveō' meaning 'to move'[4]. Ultimately, this Latin root reaches back to Proto-Indo-European '*m(y)ewh₁-' meaning 'to move'[5].
