Old English fleoge "a fly, winged insect," from Proto-Germanic *fleugon "flying insect" (source also of Old Saxon fleiga, Old Norse fluga, Middle Dutch vlieghe, Dutch vlieg, Old High German flioga, German Fliege "fly"); literally "the flying (insect)" (compare Old English fleogende "flying"), from PIE root *pleu- "to flow," which is also the source of fly (v.1).

Originally any winged insect (moths, gnats, beetles, locusts, hence butterfly, etc.) and long used by farmers and gardeners for any insect parasite. Flies figuratively for "large numbers" of anything is from 1590s. Plural flien (as in oxen, etc.) gradually normalized 13c.-15c. to -s. Fly in the ointment is from Eccles. x:1. Fly on the wall "unseen observer" first recorded 1881. No flies on _____ "no lack of activity or alertness on the part of," is attested by 1866. Meaning "fish-hook dressed to resemble an insect" is from 1580s; Fly-fishing is from 1650s. Fly-catcher "bird which eats insects on the wing" is from 1670s. The fly agaric mushroom (1788) so called because it was used as a poison for flies.

The sense of "a flight, flying" is from mid-15c. From the verb and the notion of "flapping as a wing does" comes the noun sense of "tent flap" (1810), which was extended to "strip of material sewn into a garment as a covering for buttons" or some other purpose (1844). Baseball fly ball attested by 1866. To do something on the fly is 1856, apparently from baseball.

When the catcher sees several fielders running to catch a ball, he should name the one he thinks surest to take it, when the others should not strive to catch the ball on the fly, but only, in case of its being missed, take it on the bound. ["The American Boys Book of Sports and Games," New York, 1864]

Middle English holden, earlier halden, from Old English haldan (Anglian), healdan (West Saxon), "to contain; to grasp; to retain (liquid, etc.); to observe, fulfill (a custom, etc.); to have as one's own; to have in mind (of opinions, etc.); to possess, control, rule; to detain, lock up; to foster, cherish, keep watch over; to continue in existence or action; to keep back from action," class VII strong verb (past tense heold, past participle healden), from Proto-Germanic *haldanan (source also of Old Saxon haldan, Old Frisian halda, Old Norse halda, Dutch houden, German halten "to hold," Gothic haldan "to tend").

Based on the Gothic sense (also present as a secondary sense in Old English), the verb is presumed originally in Germanic to have meant "to keep, tend, watch over" (as grazing cattle), later "to have." Ancestral sense is preserved in behold. The original past participle holden was replaced by held beginning 16c., but survives in some legal jargon and in beholden.

The modern use in the sense "lock up, keep in custody" is from 1903. Hold back in the figurative senses is from 1530s (transitive); 1570s (intransitive). To hold off is early 15c. (transitive), c. 1600 (intransitive). Hold on is early 13c. as "to maintain one's course," 1830 as "to keep one's grip on something," 1846 as an order to wait or stop.

To hold (one's) tongue "be silent" is from c. 1300. To hold (one's) own is from early 14c. To hold (someone's) hand in the figurative sense of "give moral support" is from 1935. To hold (one's) horses "be patient" is from 1842, American English; the notion is of keeping a tight grip on the reins. To have and to hold have been paired alliteratively at least since c. 1200, originally of marriage but also of real estate. To hold water in the figurative sense "be sound or consistent throughout" is from 1620s.

also dumbbell, "one of a pair of weighted bars used for exercise," by 1785, earlier (from 1711), according to OED, an apparatus like that used to ring a church bell, but without the bell (hence dumb); used for physical exercise but sometimes also to practice ringing changes. See dumb (adj.) + bell (n.). If this is right, the word must have been transferred; earlier 18c. references make mention of "pulling" or "ringing" dumb-bells and note that it can be done only indoors. The following is a footnote to the 1903 reprint of Joseph Strutt's 1801 "The Sports and Pastimes of the People of England":

The origin of the term is somewhat curious. Dumb-bells take their name by analogy, as was pointed out in Notes and Queries in 1861, "from a machine used for exercise, consisting of a rough, heavy, wooden flywheel with a rope passing through and round a spindle ... and set in motion like a church bell." This statement, however, does not sufficiently explain the transference of such a name to the short bar and rounded lead or iron ends of a hand dumb-bell. This difficulty was explained by the late Chancellor Ferguson in a paper read before the Archaeological Institute in 1895, wherein a dumb-bell apparatus, now at Lord Sackville's seat at Knowle, was described and illustrated. The roller round which the rope winds and unwinds has four iron arms, each of which has a leaden poise or ball at the end, just like the end of an ordinary hand dumb-bell. This Knowle example is fixed in an attic and the rope passed through to a gallery beneath. Anyone pulling the rope would get much the same exercise as in pulling a bell rope in a church tower, but without annoying his neighbours by the noise. There used to be a similar apparatus at New College, Oxford.

Figurative sense of "blockhead, stupid person" attested by 1918, American English college slang.

card game for two or more played with a full pack, 1834, American English, of obscure origin, perhaps from the first element of German Pochspiel, name of a card game similar to poker, from pochen "to brag as a bluff," literally "to knock, rap" (see poke (v.)). A popular alternative theory traces the word to French poque, also said to have been a card game resembling poker. "[B]ut without documentation these explanations are mere speculation" [Barnhart]. The earlier version of the game in English was called brag.

The game itself originated apparently by 1829, according to later reminiscences, in and around the lower Mississippi region, perhaps among riverboat gamblers. The original form seems to have been played with a 20-card pack (A-K-Q-J-10) evenly dealt among four players; the full-deck version was played by the 1840s.

Slang poker face (n.) "deadpan" is from 1874.

A good player is cautious or bold by turns, according to his estimate of the capacities of his adversaries, and to the impression he wants to make on them. 7. It follows that the possession of a good poker face is an advantage. No one who has any pretensions to good play will betray the value of his hand by gesture, change of countenance, or any other symptom. ["Cavendish," "Round Games at Cards," dated 1875]

To any one not very well up in these games, some parts of the book are at first sight rather puzzling. "It follows," we read in one passage, "that the possession of a good poker face" (the italics are the author's) "is an advantage." If this had been said by a Liverpool rough of his wife, the meaning would have been clear to every one. Cavendish, however, does not seem to be writing especially for Lancashire. [from a review of the above book, Saturday Review, Dec. 26, 1874]

late 14c., "pertaining or belonging to oneself, not shared, peculiar to an individual only;" of a thing, "not open to the public, for the use of privileged persons;" of a religious rule, "not shared by Christians generally, distinctive;" from Latin privatus "set apart (from what is public), belonging to oneself (not to the state), peculiar, personal," used in contrast to publicus, communis.

This is a past-participle adjective from the verb privare "to bereave, deprive, rob, strip" of anything; "to free, release, deliver" from anything, from privus "one's own, individual," from Proto-Italic *prei-wo- "separate, individual," from PIE *prai-, *prei- "in front of, before," from root *per- (1) "forward." The semantic shift would be from "being in front" to "being separate."

Old English in this sense had syndrig. Of persons, "not holding public office or employment," recorded from early 15c. Of communications, "meant to be secret or confidential," 1550s. In private "privily" is from 1580s. Related: Privately.

Private school "school owned and run by individuals, not by the government, and run for profit" is by 1650s. Private parts "the pudenda" is from 1785 (privete "the sexual parts" is from late 14c.; secret parts in the same sense is from 16c.).

Private property "property of persons in their individual, personal, or private capacity," as distinguished from property of the state or public or for public use, is by 1680s. Private enterprise "business or commercial activity privately owned and free from direct state control" is recorded by 1797; private sector "part of an economy, industry, etc. that is free from state control" is from 1948.

Private eye "private detective, person engaged unofficially in obtaining secret information for or guarding the private interests of those who employ him" is recorded from 1938, American English (Chandler). Private detective "detective who is not a member of an official police force" is by 1856.

1921, in U.S. humorist Frederick J. Allen's piece "The Goon and His Style" (Harper's Monthly Magazine, December 1921), which defines it as "a person with a heavy touch," one who lacks "a playful mind;" perhaps a made-up word, or from gony "simpleton" (1580s), which was applied by sailors to the albatross and similar big, clumsy birds. Goons were contrasted with jiggers, and the columns about them had some currency in U.S. newspapers c. 1921-25.

A goon is a person with a heavy touch as distinguished from a jigger, who has a light touch. ... Most Germans are goons; most French jiggers. ["A 'Goon' and His Style," in Lincoln State Journal, Dec. 9, 1921]

The word turns up in various places early 20c.: As a mythical monster in a children's serialized story in the U.S. from 1904, as the name of a professional wrestler in North Carolina in 1935. The goons were characters in the "Thimble Theater" comic strip (starring Popeye) by U.S. cartoonist E.C. Segar (1894-1938); they appeared in Segar's strips from mid-1930s and, though they reportedly gave children nightmares, enjoyed a burst of popularity when they appeared in animated cartoons in 1938.

The most famous was Alice the Goon, slow-witted and muscular (but gentle-natured) character who began as the Sea Hag's assistant. Segar might have got the word directly from sailors' jargon.

Later 20c. senses of the word all probably stem from this: Sense of "hired thug" is first recorded 1938 (in reference to union "beef squads" used to cow strikers in the Pacific Northwest). She also was the inspiration for British comedian Spike Milligan's "The Goon Show." Also used among American and British POWs in World War II in reference to their German guards. What are now "juvenile delinquents" were in the 1940s sometimes called goonlets.

c. 1300 (early 13c. in surname Porkuiller), "flesh of a pig as food," from Old French porc "pig, swine, boar," and directly from Latin porcus "pig, tame swine," from PIE root *porko- "young pig." Also in Middle English "a swine, a hog" (c. 1400).

Pork barrel in the literal sense "barrel in which pork is kept" is from 1801, American English; the meaning "state's financial resources (available for distribution)" is attested from 1907 (in full, national pork barrel); it was noted as an expression of U.S. President President William Howard Taft:

"Now there is a proposition that we issue $500,000,000 or $1,000,000,000 of bonds for a waterway, and then that we just apportion part to the Mississippi and part to the Atlantic, a part to the Missouri and a part to the Ohio. I am opposed to it. I am opposed to it because it not only smells of the pork barrel, but it will be the pork barrel itself. Let every project stand on its bottom." [The Outlook, Nov. 6, 1909, quoting Taft]

The magazine article that includes the quote opens with:

We doubt whether any one knows how or when, or from what application of what story, the phrase "the National pork barrel" has come into use. If not a very elegant simile, it is at least an expressive one, and suggests a graphic picture of Congressmen eager for local advantage going, one after another, to the National pork barrel to take away their slices for home consumption.

Pork in this sense is attested from 1862 (compare figurative use of bacon). Pork chop "slice of meat from the ribs of a pork" is attested from 1858. Pork pie "pie made of pastry and minced pork" is from 1732; pork-pie hat (1855) originally described a woman's style popular c. 1855-65, but also worn by men. It was distinguished by a brim turned up around the low crown, a shape that resembled a deep pork pie.

1590s, "compatriot," from French patriote (15c.) and directly from Late Latin patriota "fellow-countryman" (6c.), from Greek patriotes "fellow countryman," from patrios "of one's fathers," patris "fatherland," from pater (genitive patros) "father" (see father (n.)); with -otes, suffix expressing state or condition. Liddell & Scott write that patriotes was "applied to barbarians who had only a common [patris], [politai] being used of Greeks who had a common [polis] (or free-state)."

Meaning "loyal and disinterested lover and defender of one's country and its interests" is attested from c. 1600, but it became an ironic term of ridicule or abuse from mid-18c. in England, so that Johnson, who at first defined it as "one whose ruling passion is the love of his country," in his fourth edition added, "It is sometimes used for a factious disturber of the government."

The name of patriot had become [c. 1744] a by-word of derision. Horace Walpole scarcely exaggerated when he said that ... the most popular declaration which a candidate could make on the hustings was that he had never been and never would be a patriot. [Macaulay, "Horace Walpole," 1833]

It was somewhat revived in reference to resistance movements in overrun countries in World War II, and it has usually had a positive sense in American English, where the phony and rascally variety has been consigned to the word patrioteer (1928).

Oriana Fallaci ["The Rage and the Pride," 2002] marvels that Americans, so fond of patriotic, patriot, and patriotism, lack the root noun and are content to express the idea of patria by cumbersome compounds such as homeland. (Joyce, Shaw, and H.G. Wells all used patria as an English word early 20c., but it failed to stick.) Patriots' Day (April 19, the anniversary of the 1775 skirmishes at Lexington and Concord Bridge) was observed as a legal holiday in Maine and Massachusetts from 1894.

"companion, comrade," c. 1200, from Old English feolaga "partner, one who shares with another," from Old Norse felagi, from fe "money" (see fee) + lag, from Proto-Germanic *lagam, from PIE root *legh- "to lie down, lay." The etymological sense of fellow seems to be "one who puts down money with another in a joint venture."

Meaning "one of the same kind" is from early 13c.; that of "one of a pair" is from c. 1300. Used familiarly since mid-15c. for "any man, male person," but not etymologically masculine (it is used of women, for example, in Judges xi.37 in the King James version: "And she said unto her father, Let this thing be done for me: let me alone two months, that I may go up and down upon the mountains, and bewail my virginity, I and my fellows").

Its use can be contemptuous or dignified in English and American English, and at different times in its history, depending on who used it to whom, it has carried a tinge of condescension or insult.

University senses (mid-15c., corresponding to Latin socius) evolved from notion of "one of the corporation who constitute a college" and who are paid from its revenues. Fellow well-met "boon companion" is from 1580s, hence hail-fellow-well-met as a figurative phrase for "on intimate terms."

In compounds, with a sense of "co-, joint-," from 16c., and by 19c. also denoting "association with another." Hence fellow-traveler, 1610s in a literal sense but in 20c. with a specific extended sense of "one who sympathizes with the Communist movement but is not a party member" (1936, translating Russian poputchik).

Fellow-countrymen formerly was one of the phrases the British held up to mock the Americans for their ignorance, as it is redundant to say both, until they discovered it dates from the 1580s and was used by Byron and others.
