Etymology: The most striking turn in this word's history is that it once meant a snake as much as a wriggling grub. Old English "wyrm" and its Proto-Germanic ancestor ""wurmiz" covered serpents, dragons and small creeping creatures alike, and that broad sense survives in cognates across the Germanic languages: Gothic "waurms" meant "snake," Danish and Swedish "orm" still do, and Icelandic "ormur" is the same word. English narrowed the term over the centuries to the soft, legless creatures we know today, while its near-twin "wyrm" was later borrowed back directly from Old English to name serpents and dragons, a usage that lives on in fantasy writing. Behind all of this lies an Indo-European root, ""wr̥mis," which carried the sense of "worm" or "larva," and which may connect to a verb meaning "to turn," a nod to the creature's twisting motion. The same root gave Latin "vermis," the source of "vermin" and a doublet of the English word, so the two come from one ancestor by separate routes. In computing, the word took on a new life when John Brunner used it in his 1975 novel "The Shockwave Rider," where a self-replicating program spreads through a network. The sense of a program that copies itself across systems grew from that fictional usage.
