Sociopath → It is formed from "socio-" (from Latin "socius", meaning companion or ally) and "-path" (from Greek "pathos", meaning feeling or suffering). The term describes a person who has a lack of empathy or regard for social relationships, indicating a disconnection from the feelings of others.
Think of 'socio-' meaning 'companion' and '-path' relating to 'feeling' — a sociopath is someone who struggles with feelings in social relationships.
