spiderling (n.)

late 14c., spydyr, spither, earlier spiþre, spiþur, spiþer (mid-14c.), from Old English spiðra, from Proto-Germanic *spin-thron- (cognate with Danish spinder), etymologically "spinner," from PIE root *(s)pen- "to draw, stretch, spin" + formative or agential *-thro. The connection with the root is more transparent in other Germanic cognates, such as Middle Low German, Middle Dutch, Middle High German, German spinne, Dutch spin "spider."

The loss of -n- before spirants is regular in Old English (compare goose (n.), tooth). For shift of -th- to -d- compare murder (n.), burden (n.), rudder; also see D.

The male is commonly much smaller than the female, and in impregnating the female runs great risk of being devoured. The difference in sizes is as if the human female should be some 60 or 70 feet tall. [Century Dictionary entry for "spider"]

Not the common word in Old or Middle English, which identified the creatures as loppe (Chaucer's usual word), lobbe. Old English also had atorcoppe (Middle English attercop, literally "poison-head"), and (from Latin aranea), renge; Middle English had araine, "spider," via Old French from the same Latin word (see arachnid). Another Old English word was gangewifre "a weaver as he goes."

In literature, often a figure of cunning, skill, and industry as well as venomous predation; in 17c. English used figuratively for venomousness and thread-spinning but also sensitivity (to vibrations), lurking, and independence. As the name for a type of two-pack solitaire, it is attested from 1890, probably based on resemblance of the layout of the decks in the original form of the game (see "Tarbart," "Games of Patience," 1901, p. 49).

Spider crab is from 1710, used of various species with long, slender legs and comparatively small bodies; the spider monkey (1764) is so called for its long limbs. Spider-catcher (1570s) was an old vague term of abuse.

diminutive word-forming element, early 14c., from Old English -ling a nominal suffix (not originally diminutive), from Proto-Germanic *-linga-; attested in historical Germanic languages as a simple suffix, but probably representing a fusion of two suffixes: 1. that represented by English -el (1), as in thimble, handle; and 2. -ing, suffix indicating "person or thing of a specific kind or origin;" in masculine nouns also "son of" (as in farthing, atheling, Old English horing "adulterer, fornicator"), from PIE *-(i)ko- (see -ic).

Both these suffixes had occasional diminutive force, but this was only slightly evident in Old English -ling and its equivalents in Germanic languages except Norse, where it commonly was used as a diminutive suffix, especially in words designating the young of animals (such as gæslingr "gosling"). Thus it is possible that the diminutive use that developed in Middle English is from Old Norse.
