Etymology: Fluoroscopic is a technical coinage built from "fluoroscope" plus the adjective-forming suffix "-ic", so its history is essentially the history of the machine it describes. The first half, "fluoro-", refers to fluorescence, the glow that certain minerals give off under radiation, which is what early screens used to make X-ray images visible. The second half, "-scope", comes from the Greek "skopein", meaning "to look at" or "to examine", as in "microscope" and "telescope." The "-ic" ending entered English through Latin "-icus", reached Middle English as "-ik", and became the modern "-ic" as spelling settled. It is the same suffix found in "electric" or "photographic," and it simply turns the noun "fluoroscope" into a word meaning "relating to" or "done by means of" that instrument. Taken together, the word describes the technique of watching the inside of the living body move on a screen rather than capturing a single still image.
