The word "scanner" derives from the verb "scan," which entered English in the 14th century from Latin scandere ("to climb, analyze"). The original sense of "analyze metrical verse" expanded to "examine thoroughly" by the 19th century. The suffix "-er" (from Old English -ere) denotes an agent or tool, creating "scanner" in the early 20th century for devices that systematically capture or analyze data.
