hypnotherapist

The word 'hypnotherapist' is a modern English compound built from classical elements. Its core, 'hypno-', originates from the Greek hypnos, the personification and god of sleep, reflecting the sleep-like trance central to the practice. This is combined with '-therapy', from Greek therapeia, meaning 'healing' or 'attendance', which entered English via Latin to denote a course of medical treatment. The agent suffix '-ist', also of Greek origin via Latin, specifies a practitioner. Thus, the term's literal construction—'a practitioner of sleep-healing'—logically evolved into its modern professional meaning: a specialist who uses hypnotic states for therapeutic purposes.
