Etymology: The most surprising thing about this word is how little of it is old. Its second half, "therapist," traces back to ancient Greek "therapeuein," meaning to attend or serve, and by way of the Greek "therapeia" (healing, care) it reached modern European languages as the term "therapy." The Latin-derived suffix "-ist" was attached to form "therapist" in English, and the word "radiotherapist" then joined that stem with "radio-," from Latin "radius" (a ray or spoke of a wheel). Put together, the compound describes a specialist in treatment by radiation. The first part, "radio-," had by the time of this coinage come to mean rays of energy generally, a sense that developed far from the Greek and Latin originals. The ancient Greeks who used "therapon" meant an attendant or servant, not a clinician, so the modern medical sense is a later narrowing of that old idea of service. The compound is a plain formation from existing parts rather than a single invention with a known inventor, so there is no single coiner to credit.

Synonyms: radiation therapist, oncology technician, radiation oncologist, therapist, cancer specialist
