bulge [bulge 词源字典]: bulge: [13] Etymologically, bulge and budget are the same word, and indeed when English first acquired bulge it was as a noun, with, like budget, the sense ‘pouch’. It came from Old French bouge ‘leather bag’, a descendant of Latin bulga, which may have been of Gaulish origin (medieval Irish bolg ‘bag’ has been compared). The word’s present-day connotations of ‘swelling’ and ‘protruding’ presumably go back to an early association of ‘pouches’ with ‘swelling up when filled’ (compare the case of bellows and belly, which originally meant ‘bag’, and came from a source which meant ‘swell’), but curiously, apart from an isolated instance around 1400 when bulge is used for a ‘hump on someone’s back’, there is no evidence for this meaning in English before the 17th century.

Additionally, from the 17th to the 19th centuries bulge was used for the ‘bottom of a ship’s hull’; it has now been superseded in this sense by bilge [15], which may well be a variant form.
=> bilge, budget[bulge etymology, bulge origin, 英语词源]
cocksucker (n.): 1890s, "one who does fellatio" (especially a male homosexual); 1920s as "contemptible person," American English, from cock (n.1) in phallic sense + sucker (n.). Used curiously for aggressively obnoxious men; the ancients would have recoiled at this failure to appreciate the difference between passive and active roles; Catullus, writing of his boss, employs the useful Latin insult irrumator, which means "someone who forces others to give him oral sex," hence "one who treats people with contempt."
cordite (n.): smokeless explosive, 1889, from cord + -ite (2); so called for its "curiously string-like appearance" in the words of a newspaper of the day.
ordeal (n.): Old English ordel, ordal, "trial by physical test," literally "judgment, verdict," from Proto-Germanic noun *uz-dailjam (cognates: Old Saxon urdeli, Old Frisian urdel, Dutch oordeel, German urteil "judgment"), literally "that which is dealt out" (by the gods), from *uzdailijan "share out," related to Old English adælan "to deal out" (see deal (n.1)). Curiously absent in Middle English, and perhaps reborrowed 16c. from Medieval Latin or Middle French, which got it from Germanic.

The notion is of the kind of arduous physical test (such as walking blindfolded and barefoot between red-hot plowshares) that was believed to determine a person's guilt or innocence by immediate judgment of the deity, an ancient Teutonic mode of trial. English retains a more exact sense of the word; its cognates in German, etc., have been generalized.

Metaphoric extension to "anything which tests character or endurance" is attested from 1650s. The prefix or- survives in English only in this word, but was common in Old English and other Germanic languages (Gothic ur-, Old Norse or-, etc.) and originally was an adverb and preposition meaning "out."
rabbit (n.): late 14c., "young of the coney," from Walloon robète or a similar French dialect word, diminutive of Flemish or Middle Dutch robbe "rabbit," of unknown origin. "A Germanic noun with a French suffix" [Liberman]. The adult was a coney (q.v.) until 18c.
Zoologically speaking, there are no native rabbits in the United States; they are all hares. But the early colonists, for some unknown reason, dropped the word hare out of their vocabulary, and it is rarely heard in American speech to this day. When it appears it is almost always applied to the so-called Belgian hare, which, curiously enough, is not a hare at all, but a true rabbit. [Mencken, "The American Language"]
Rabbit punch "chop on the back of the neck" so called from resemblance to a gamekeeper's method of dispatching an injured rabbit. Pulling rabbits from a hat as a conjurer's trick recorded by 1843. Rabbit's foot "good luck charm" first attested 1879, in U.S. Southern black culture. Earlier references are to its use as a tool to apply cosmetic powders.
[N]ear one of them was the dressing-room of the principal danseuse of the establishment, who was at the time of the rising of the curtain consulting a mirror in regard to the effect produced by the application of a rouge-laden rabbit's foot to her cheeks, and whose toilet we must remark, passim, was not entirely completed. ["New York Musical Review and Gazette," Nov. 29, 1856]
Rabbit ears "dipole television antenna" is from 1950. Grose's 1785 "Dictionary of the Vulgar Tongue" has "RABBIT CATCHER. A midwife."
satyr (n.): woodland deity, companion of Bacchus, late 14c., from Latin satyrus, from Greek satyros, of unknown origin. In pre-Roman Greek art, a man-like being with the tail and ears of a horse; the modern conception of a being part man, part goat is from Roman sculptors, who seem to have assimilated them to the fauns of native mythology. In some English bibles used curiously to translate Hebrew se'irim, a type of hairy monster superstitiously believed to inhabit deserts.
Triscuit (n.): proprietary name for a type of cracker, 1906, curiously from tri- + biscuit.
ventriloquy (n.): 1580s, from Late Latin ventriloquus, from Latin venter (genitive ventris) "belly" (see ventral) + loqui "speak" (see locution). Related: Ventriloquial; ventriloquize.

Patterned on Greek engastrimythos, literally "speaking in the belly," which was not originally an entertainer's trick but rather a rumbling sort of internal speech, regarded as a sign of spiritual inspiration or (more usually) demonic possession. Reference to the modern activity so called seems to have begun early 18c., and by 1797 it was being noted that this was a curiously inappropriate word to describe throwing the voice.
