Cognition
Etymology

The word cognition dates back to the 15th century, where it meant " thinking and awareness". The term comes from the Latin noun cognitio ('examination', 'learning', or 'knowledge'), derived from the verb cognosco, a compound of con ('with') and gnōscō ('know'). The latter half, gnōscō, itself is a cognate of a Greek verb, gi(g)nósko (γι(γ)νώσκω, ' I know,' or 'perceive ').
