cognitive

The word 'cognitive' is built upon the Latin root cogn-, which stems from the verb cognoscere, meaning 'to get to know' or 'to recognize'. This Latin verb itself is a compound of co- (an intensive prefix meaning 'altogether') and gnoscere (the older form of noscere, 'to know'), tracing back to the Proto-Indo-European root ǵneh₃-, the ultimate source for words related to knowing. The suffix -itive was adopted into English via Latin -itivus, forming adjectives that denote a relationship or pertaining to an action. Thus, the literal construction 'pertaining to knowing' evolved into the modern psychological term describing all processes of the mind involved in knowing, such as perception, memory, and reasoning.

Structure: cogn (know) + itive (adjective suffix) cogn (from Latin cognoscere, meaning 'to get to know, recognize, become acquainted with'); itive (a modern English adjective-forming suffix, often derived from Latin -itivus, indicating a tendency, connection, or quality).
