Etymology: The word is a plain formation: "radiology" with the agent suffix "-ist" added, naming the person who practises that field. The suffix has a long pedigree, running from Ancient Greek "-istēs", which marked someone who practised or followed a particular activity, through Latin "-ista", into Old French "-iste" and then Middle English "-ist". By the time English speakers were building new professional titles from it, the suffix was thoroughly established. The base word "radiology" is the more recent coinage. It combines "radio-", from Latin "radius" meaning "ray", with the Greek-derived "-logy", meaning "study of". Physicians began using X-rays and related rays for diagnosis in the late nineteenth century, so a term for the discipline arose alongside those techniques, and "radiologist" followed as the name for those who worked in it.

Synonyms: radiographer, x-ray technician
