'nonpsychic' originates from modern English, specifically from the prefix 'non-' (from Latin 'non', meaning 'not') combined with the adjective 'psychic' (from Greek 'psȳkhē').

'psychic' came from Greek 'psȳkhē' (soul, mind) via Late Latin and French 'psychique', and was adopted into modern English as 'psychic'; 'non-' as a productive English prefix (from Latin 'non') was attached to form 'nonpsychic'.

Originally 'psychic' related to the 'soul' or 'mind' (Greek) and later came to be used for paranormal mental phenomena; 'nonpsychic' therefore evolved as a negated form meaning 'not having or exhibiting such paranormal mental abilities'.
