cognitive (English)
Where does "cognitive" come from?
The English adjective 'cognitive' derives from Medieval Latin 'cognitīvus'[1], which was formed using the adjective suffix '-īvus'[1][3]. Its base is the Latin verb 'cognōscō', meaning 'I get to know'[1][3] or 'know, recognise'[2], compounded from the intensive prefix 'con-' and 'gnōscō', meaning 'to know'[4]. This verb traces back through Proto-Italic '*gnōskō'[5][6][8] to the Proto-Indo-European present formation '*ǵn̥h₃sḱéti'[5][7], an extension of the ancient root '*ǵneh₃-', signifying 'to recognise, to know'[7]. Over time, these roots of knowing and perception evolved into English terminology specifically focused on intellectual and logical mental processes.
