cognition (English)
Where does "cognition" come from?
The word cognition reaches back to the Proto-Indo-European root *ǵneh₃-, meaning 'to know' or 'recognize.' It evolved into Latin as the compound verb cognoscere, merging the prefix 'con-' (together) with the root to signify 'getting to know' or 'becoming acquainted.' This eventually gave rise to the Latin noun cognitio and the Middle English cognicioun before settling into modern English as the process of acquiring knowledge and understanding.
