Etymology: The "-scope" in this word is the same Greek root that gives us "telescope" and "microscope," but here it arrives with a much older and stranger job. Ancient Greek "keraunoskopia" meant divination from thunder and lightning, the practice of reading omens in storms. The "keraunos" part meant "thunderbolt," and "skopein" meant "to look at" or "to consider," so the original sense was closer to watching the bolts for meaning than to measuring them. The modern instrument took its name from that Greek noun, with the neuter ending "-eion" marking a place or device, so the thing was named for the act of observing lightning. English speakers formed the word from the combining forms "cerauno-" and "-scope," following the pattern of older scientific coinages. Its name is thus a modern construction built on ancient parts rather than a term the Greeks used for a device.
