dragnet

The word 'dragnet' is a transparent English compound formed from two native Germanic elements. The first element, 'drag', originates from the Old Norse verb draga, meaning to pull or draw, which entered the English lexicon during the Viking Age. The second element, 'net', has an even older pedigree, descending from the Old English nett, a tool for ensnaring. Literally describing a "net that is dragged," the term first applied to fishing gear. Its semantic expansion into law enforcement in the 19th century is a vivid metaphor: a coordinated police operation is likened to systematically pulling a net through an area to catch everything within it, transforming a concrete tool into an abstract concept of systematic search and capture.

Structure: drag (pull) + net (mesh) - drag: From Middle English draggen, likely from Old Norse draga (to draw, pull). In this compound, it functions as a verb root describing the action performed with the object. - net: From Old English nett (a fabric of open texture for catching), from Proto-Germanic natją. In this compound, it functions as the noun root specifying the object being used.
