fly [fly 词源字典]: fly: [OE] Historically, ‘move through the air’ is something of a secondary semantic development for fly. Its distant Indo-European ancestor, *pleu-, denoted rapid motion in general, and in particular ‘flowing’ or ‘floating’, and it produced such offspring as Greek pléo ‘sail, float’ and Sanskrit plu- ‘sail, swim’, as well as English fleet, flood, flow, fowl, plover, and pluvial.

An extension to that base, *pleuk-, gave rise to Lithuanian plaukti ‘float, sail, swim’, and to prehistoric West and North Germanic *fleugan, source of German fliegen, Dutch vliegen, Swedish flyga, and English fly, all meaning ‘move with wings’. The insect-name fly is also of considerable antiquity, going back to a prehistoric Germanic derivative *fleugōn or *fleugjōn, but the origins of the adjective fly ‘crafty, sharp’ [19] are not known.

gossamer: gossamer: [14] It would be pleasant to think that gossamer, originally ‘fine cobwebs’, is a descendant of an earlier goose-summer, but unfortunately there is not enough evidence to make this more than a conjecture. The theory goes as follows: mid-autumn is a time when geese for the table are plentiful (November was once known as gänsemonat ‘geese-month’ in German), and so a warm period around then might have been termed goose-summer (we now call it an Indian summer); the silken filaments of gossamer are most commonly observed floating in the air on such warm autumnal days; and so the spiders’ webs were christened with the name of the season.
pontoon: pontoon: English has two words pontoon. The earlier, ‘floating structure’ [17], comes via French ponton from Latin pontō ‘bridge made of boats’, a derivative of pōns ‘bridge’. (Pontō, presumably the same word, was also used for a sort of Gaulish boat, and in that sense is the source of English punt.) Pontoon the card game [20] is an alteration of French vingt-et-un ‘twenty-one’ (the perfect score in pontoon being twenty-one) based on the other pontoon.
suds: suds: [16] Suds was probably borrowed from Middle Dutch sudse ‘marsh, swamp’ (it was used in the East Anglian dialect for ‘muddy swamp water’ or ‘flood water’, and probably the notion of scum or flotsam on such water led on to ‘floating bubbles, lather’ – first recorded at the end of the 15th century). The word’s ultimate source is no doubt the prehistoric Germanic base *suth- ‘boil’, which also produced English seethe and sodden.
=> seethe, sodden
ambergris (n.): early 15c., from Middle French ambre gris "gray amber" (see amber), "a wax-like substance of ashy colour, found floating in tropical seas, a morbid secretion from the intestines of the sperm-whale. Used in perfumery, and formerly in cookery" [OED]. Its origin was a mystery in Johnson's day, and he records nine different theories. King Charles II's favorite dish was said to be eggs and ambergris [Macauley, "History of England"]. French gris is from Frankish *gris or some other Germanic source (cognates: Dutch grijs, Old High German gris; see gray (adj.)).
Praise is like ambergris; a little whiff of it, by snatches, is very agreeable; but when a man holds a whole lump of it to his nose, it is a stink and strikes you down. [Pope, c. 1720]
fleet (n.): Old English fleot "a ship, raft, floating vessel," also, collectively, "means of sea travel; boats generally," from fleotan "to float" (see fleet (v.)). Sense of "naval force, group of ships under one command" is in late Old English. The more usual Old English word was flota "a ship," also "a fleet; a sailor." The fleet for "the navy" is from 1712.

The Old English word also meant "estuary, inlet, flow of water," especially the one into the Thames near Ludgate Hill, which lent its name to Fleet Street (home of newspaper and magazine houses, standing for "the English press" since 1882), Fleet prison (long used for debtors), etc.
fleeting (adj.): early 13c., "fickle, shifting, unstable," from Old English fleotende "floating, drifting," later "flying, moving swiftly," from present participle of fleotan "to float, drift, flow" (see fleet (v.)). Meaning "existing only briefly" is from 1560s. Related: Fleetingly.
float (v.): late Old English flotian "to rest on the surface of water" (intransitive; class II strong verb; past tense fleat, past participle floten), from Proto-Germanic *flotan "to float" (cognates: Old Norse flota, Middle Dutch vloten, Old High German flozzan, German flössen), from *flot-, from PIE *pleud-, extended form of root *pleu- "to flow" (see pluvial).

Meaning "drift about, hover passively" is from c. 1300. Transitive sense of "to lift up, cause to float" (of water, etc.) is from c. 1600; that of "set (something) afloat" is from 1778 (originally of financial operations). Of motion through air, from 1630s. Meaning "hover dimly before the eyes" is from 1775. Related: Floated; floating. A floating rib (by 1802) is so called because the anterior ends are not connected to the rest.
float (n.): apparently an early Middle English merger of three related Old English nouns, flota "boat, fleet," flote "troop, flock," flot "body of water, sea;" all from the source of float (v.). The early senses were the now-mostly-obsolete ones of the Old English words: "state of floating" (early 12c.), "swimming" (mid-13c.); "a fleet of ships; a company or troop" (c. 1300); "a stream, river" (early 14c.). From c. 1300 as an attachment for buoyancy on a fishing line or net; early 14c. as "raft." Meaning "platform on wheels used for displays in parades, etc." is from 1888, probably from earlier sense of "flat-bottomed boat" (1550s). As a type of fountain drink, by 1915.
Float.--An ade upon the top of which is floated a layer of grape juice, ginger ale, or in some cases a disher of fruit sherbet or ice cream. In the latter case it would be known as a "sherbet float" or an "ice-cream float." ["The Dispenser's Formulary: Or, Soda Water Guide," New York, 1915]

Few soda water dispensers know what is meant by a "Float Ice Cream Soda." This is not strange since the term is a coined one. By a "float ice cream soda" is meant a soda with the ice cream floating on top, thus making a most inviting appearance and impressing the customer that you are liberal with your ice cream, when you are not really giving any more than the fellow that mixes his ice cream "out of sight." ["The Spatula," Boston, July, 1908]
flotsam (n.): c. 1600, from Anglo-French floteson, from Old French flotaison "a floating" (Modern French flottaison), from floter "to float, set afloat" (of Germanic origin; see flotilla) + -aison, from Latin -ation(em). Spelled flotsen in English till mid-19c. when it altered, perhaps under influence of many English words in -some. Folk-etymologized in dialect as floatsome.

In British law, flotsam are goods found floating on the sea as a consequence of a shipwreck or action of wind or waves; jetsam are things cast out of a ship in danger of being wrecked, and afterward washed ashore, or things cast ashore by the sailors. Whatever sinks is lagan. Flotsam and jetsam figuratively for "odds and ends" is attested by 1861.
halcyon (adj.): "calm, quiet, peaceful," 1540s, in halcyon dayes (translating Latin alcyonei dies, Greek alkyonides hemerai), 14 days of calm weather at the winter solstice, when a mythical bird (also identified with the kingfisher) was said to breed in a nest floating on calm seas. The name of this fabulous bird is attested in Middle English as alcioun (late 14c.). The name is from Latin halcyon, alcyon, from Greek halkyon, variant (perhaps a misspelling) of alkyon "kingfisher," a word of unknown origin. The explanation that this is from hals "sea; salt" (see halo-) + kyon "conceiving," present participle of kyein "to conceive," literally "to swell" (see cumulus) probably is ancient folk-etymology to explain a loan-word from a non-Indo-European language. Identified in mythology with Halcyone, daughter of Aeolus, who when widowed threw herself into the sea and became a kingfisher.
meteoroid (n.): "rock floating in space, which becomes a meteor when it enters Earth's atmosphere," formed in English, 1865, from meteor + -oid.
moorings (n.): 1744, "ropes, etc., by which a floating thing is made fast," from mooring. Figurative sense is from 1851.
pack (n.): "bundle," early 13c., probably from a Low German word (compare Middle Dutch pac, pack "bundle," Middle Low German pak, Middle Flemish pac, attested from late 12c.), originally a term of wool traders in Flanders; or possibly from Old Norse pakki. All are of unknown origin.

Italian pacco is a Dutch loan word; French pacque probably is from Flemish. Meaning "set of persons" (usually of a low character) is c. 1300, older than sense of "group of hunting animals" (early 15c.). Extended to collective sets of playing cards (1590s), floating ice (1791), cigarettes (1924), and submarines (1943). Meaning "knapsack on a frame" is attested from 1916. Pack of lies first attested 1763.
pluvial (adj.): 1650s, "pertaining to rain," from French pluvial (12c.), from Latin pluvialis "pertaining to rain, rainy, rain-bringing," from (aqua) pluvia "rain (water)," from fem. of pluvius "rainy," from plovere "to rain," from PIE root *pleu- "to flow, to swim" (cognates: Sanskrit plavate "navigates, swims;" Greek plynein "to wash," plein "to navigate," ploein "to float, swim," plotos "floating, navigable;" Armenian luanam "I wash;" Old English flowan "to flow;" Old Church Slavonic plovo "to flow, navigate;" Lithuanian pilu, pilti "to pour out," plauju, plauti "to swim, rinse").
punt (n.2): "flat-bottomed river boat," late Old English punt, perhaps an ancient survival of British Latin ponto "flat-bottomed boat" (see OED), a kind of Gallic transport (Caesar), also "floating bridge" (Gellius), from Latin pontem (nominative pons) "bridge" (see pontoon). Or from or influenced by Old French cognate pont "large, flat boat."
raft (n.1): "floating platform," late 15c., originally "rafter" (c. 1300), from a Scandinavian source such as Old Norse raptr "log" (Old Norse -pt- pronounced as -ft-), related to Middle Low German rafter, rachter "rafter" (see rafter).
skim (v.): early 15c. (skimmer, the utensil, is attested from late 14c.), "to clear (a liquid) from matter floating on the surface, lift the scum from," from Old French escumer "remove scum," from escume (Modern French écume) "scum," from a Germanic source (compare Old High German scum "scum," German Schaum; see scum). Meaning "to throw (a stone) so as to skip across the surface of (water) is from 1610s. Meaning "to move lightly and rapidly over the surface of" is from 1650s, from the motion involved in skimming liquid; that of "to glance over carelessly" (in reference to printed matter) recorded by 1799. Related: Skimmed; skimming.
supernatant (adj.): "floating on the surface," 1660s, from Latin supernatantem (nominative supernatans), present participle of supernatare "to swim above," from super (see super-) + natare "to swim," frequentative of nare "to swim" (see natatorium). Related: Supernatation (1620s).
torpedo (n.): 1520s, "electric ray" (flat fish that produces an electric charge to stun prey or for defense), from Latin torpedo "electric ray," originally "numbness, sluggishness" (the fish so called from the effect of being jolted by the ray's electric discharges), from torpere "be numb" (see torpor).
Torpedo. A fish which while alive, if touched even with a long stick, benumbs the hand that so touches it, but when dead is eaten safely. [Johnson]
