Word Origin & History

worm 
O.E. wurm, variant of wyrm "serpent, dragon," also in later O.E. "earthworm," from P.Gmc. *wurmiz (cf. O.S., O.H.G., Ger. wurm, O.Fris., Du. worm, O.N. ormr, Goth. waurms "serpent, worm"), from PIE *wrmi-/*wrmo- "worm" (cf. Gk. rhomos, L. vermis "worm," O.Rus. vermie "insects," Lith. varmas "insect, gnat"), possibly from base *wer- "turn" (see versus). The ancient category of these was much more extensive than the modern, scientific, one and included serpents, scorpions, maggots, and the supposed causes of certain diseases. In Eng., the -o- was a scribal substitution to avoid confusion of -u- and -r- (as also in some, come, monk etc.). As an insult meaning "abject, miserable person" it dates from O.E. The verb meaning "to move like a worm" is recorded from 1610, in fig. senses (attested from 1627) suggesting patient, sinuous progress.

Bible Dictionary

Worm

(1.) Heb. sas (Isa. 51:8), denotes the caterpillar of the clothes-moth. (2.) The manna bred worms (tola'im), but on the Sabbath there was not any worm (rimmah) therein (Ex. 16:20, 24). Here these words refer to caterpillars or larvae, which feed on corrupting matter. These two Hebrew words appear to be interchangeable (Job 25:6; Isa. 14:11). Tola'im in some places denotes the caterpillar (Deut. 28:39; Jonah 4:7), and rimmah, the larvae, as bred from putridity (Job 17:14; 21:26; 24:20). In Micah 7:17, where it is said, "They shall move out of their holes like worms," perhaps serpents or "creeping things," or as in the Revised Version, "crawling things," are meant. The word is used figuratively in Job 25:6; Ps. 22:6; Isa. 41:14; Mark 9:44, 46, 48; Isa. 66:24.
