Online Etymology Dictionary

vocabulary (n.): 1530s, "list of words with explanations," from Medieval Latin vocabularium "a list of words," from Latin vocabulum "word, name, noun," from vocare "to name, call," related to vox "voice," from PIE root *wekw- "give vocal utterance, speak" (see voice (n.)). Meaning "range of words in the language of a person or group" is first attested 1753.
lexical (adj.): "relating to the vocabulary of a language," 1833, from a Latinized form of Greek lexikos "pertaining to words" (see lexicon) + -al (1). Related: Lexically.
galvanization (n.): 1798, formed as a noun of state to go with the vocabulary of galvanism; perhaps immediately from French galvanisation (1797 in the "Annales de chimie et de physique").
feasible (adj.): "capable of being done, accomplished or carried out," mid-15c., from Anglo-French faisible, from Old French faisable "possible, that may be done; easy, convenient," from fais-, stem of faire "do, make," from Latin facere "to make, do, perform" (see factitious). Fowler recommends this word only for those "who feel that the use of an ordinary word for an ordinary notion does not do justice to their vocabulary or sufficiently exhibit their cultivation."
inkhorn (n.): late 14c., "small portable vessel (originally made of horn) for holding ink," from ink (n.) + horn (n.). Used attributively from 1540s ("Soche are your Ynkehorne termes," John Bale) as an adjective for things (especially vocabulary) supposed to be beloved by scribblers, pedants, and bookworms. An Old English word for the thing was blæchorn.
helmet (n.): mid-15c., perhaps a diminutive of Middle English helm (see helm (n.2)). But Barnhart and OED say from Middle French helmet (Modern French heaume), diminutive of helme "helmet," from the same Germanic source as helm (n.2). "Middle English Dictionary" points to both without making a choice. "Old English helm never became an active term in the standard vocabulary of English" [Barnhart].
gurgle (v.): early 15c., medical term for "gurgling heard in the abdomen," a native, echoic formation, or ultimately from Latin gurguliare, perhaps via Dutch, German gurgeln. Extended (non-anatomical) use, in reference to water over stones, etc., is first recorded 1713. "This phenomenon of long specialized use before becoming a part of the general vocabulary is often found in English" [Barnhart]. Related: Gurgled; gurgling.
lark (n.2): "spree, frolic, merry adventure," 1811, slang, of uncertain origin. Possibly a shortening of skylark (1809), sailors' slang for "play rough in the rigging of a ship" (larks were proverbial for high-flying). Or perhaps it is an alteration of English dialectal or colloquial lake/laik "to play, frolic, make sport" (c. 1300, from Old Norse leika "to play," from PIE *leig- (3) "to leap") with intrusive -r- common in southern British dialect. The verb lake, considered characteristic of Northern English vocabulary, is the opposite of work but lacks the other meanings of play. As a verb, from 1813. Related: Larked; larking.
adjective: late 14c., as an adjective, "adjectival," in noun adjective, from Old French adjectif (14c.), from Latin adjectivum "that is added to (the noun)," neuter of adjectivus "added," from past participle of adicere "to throw or place (a thing) near," from ad- "to" (see ad-) + comb. form of iacere "to throw" (see jet (v.)). Also as a noun from late 14c. In 19c. Britain, the word itself often was a euphemism for the taboo adjective bloody.
They ... slept until it was cool enough to go out with their 'Towny,' whose vocabulary contained less than six hundred words, and the Adjective. [Kipling, "Soldiers Three," 1888]
hep (1): "aware, up-to-date," first recorded 1908 in "Saturday Evening Post," but said to be underworld slang, of unknown origin. Variously said to have been the name of "a fabulous detective who operated in Cincinnati" [Louis E. Jackson and C.R. Hellyer, "A Vocabulary of Criminal Slang," 1914] or a saloonkeeper in Chicago who "never quite understood what was going on ... (but) thought he did" ["American Speech," XVI, 154/1]. Taken up by jazz musicians by 1915. With the rise of hip (adj.) by the 1950s, the use of hep ironically became a clue that the speaker was unaware and not up-to-date.
hike (v.): 1809, hyke "to walk vigorously," an English dialectal word of unknown origin. A yike from 1736 answers to the sense. Not in widespread popular use until early 20c.
HIKE, v. to go away. It is generally used in a contemptuous sense. Ex. "Come, hike," i.e. take yourself off; begone. [Rev. Robert Forby, "The Vocabulary of East Anglia," London, 1830]
Sense of "pull up" (as pants) first recorded 1873 in American English, and may be a variant of hitch; extended sense of "raise" (as wages) is 1867. Related: Hiked; hiking.
backwood (n.): 1709, American English, from back (adj.) + wood (n.) "forested tract." Also backwoods. As an adjective, from 1784.
BACKWOODSMEN. ... This word is commonly used as a term of reproach (and that, only in a familiar style,) to designate those people, who, being at a distance from the sea and entirely agricultural, are considered as either hostile or indifferent to the interests of the commercial states. [John Pickering, "A Vocabulary, or Collection of Words and Phrases Which Have Been Supposed to be Peculiar to the United States of America," Boston, 1816]
lexicon (n.): c. 1600, "a dictionary, a word-book," from Middle French lexicon or directly from Modern Latin lexicon, from Greek lexikon (biblion) "word (book)," from neuter of lexikos "pertaining to words," from lexis "word, a speaking, saying, speech, phrase; way of speaking, diction," from legein "to say" (see lecture (n.)).

Especially of dictionaries of Greek, Syriac, Hebrew, or Arabic, because these typically were written in Latin, and in Modern Latin lexicon (not dictionarius) was the preferred name for a word-book. The modern sense of "vocabulary proper to some sphere of activity" (1640s) is a figurative extension.
rung (n.): Old English hrung "rod, bar," from Proto-Germanic *khrungo (source also of Middle Low German runge, Old High German runga "stake, stud, stave," German Runge "stake, stud, stave," Middle Dutch ronghe, Dutch rong "rung," Gothic hrugga "staff"), of unknown origin with no connections outside Germanic. Sense in English narrowed to "round or stave of a ladder" (first attested late 13c.), but usage of cognate words remains more general in other Germanic languages.
This [rungs] has generally been considered as a mere corruption of rounds; and people of education use only this latter word. [John Pickering, "A Vocabulary or Collection of Words and Phrases which have been Supposed to be Peculiar to the United States of America," Boston, 1816]
-ate (2): verbal suffix for Latin verbs in -are, identical with -ate (1). Old English commonly made verbs from adjectives by adding a verbal ending to the word (such as gnornian "be sad, mourn," gnorn "sad, depressed"), but as the inflections wore off English words in late Old and early Middle English, there came to be no difference between the adjective and the verb in dry, empty, warm, etc. Thus accustomed to the identity of adjectival and verbal forms of a word, the English, when they began to expand their Latin-based vocabulary after c. 1500, simply made verbs from Latin past-participial adjectives without changing their form (such as aggravate, substantiate) and it became the custom that Latin verbs were Englished from their past participle stems.
P: a rare letter in the initial position in Germanic, in part because by Grimm's Law PIE p- became Germanic f-; even with the early Latin borrowings in Old English, -p- takes up a little over 4 pages in J.R. Clark Hall's "Concise Anglo-Saxon Dictionary," compared to 31 pages for B and more than 36 for F. But it now is the third-most-common initial letter in the English vocabulary, and with C and S comprises nearly a third of the dictionary, a testimony to the flood of words that have entered the language since 1066 from Latin, Greek, and French.

To mind one's Ps and Qs (1779), possibly is from confusion of these letters among children learning to write. Another theory traces it to old-time tavern-keepers tracking their patrons' bar tabs in pints and quarts. But see also to be P and Q (1610s), "to be excellent," a slang phrase said to derive from prime quality.
grass widow (n.): 1520s, the earliest recorded sense is "mistress;" the allusion to grass is not clear, but it commonly was believed to refer to casual bedding (compare bastard and German Strohwitwe, literally "straw-widow," and compare the expression give (a woman) a grass gown "roll her playfully on the grass" (1580s), also euphemistic for the loss of virginity). Revived late 18c. as "one that pretends to have been married, but never was, yet has children;" in early 19c. use it could mean "married woman whose husband is absent" (and often presumed, but not certainly known to be, dead), also often applied to a divorced or discarded wife or an unmarried woman who has had a child. Both euphemistic and suggestive.
[G]rasse wydowes ... be yet as seuerall as a barbours chayre and neuer take but one at onys. [More, 1528]

GRASS WIDOW, s. a forsaken fair one, whose nuptials, not celebrated in a church, were consummated, in all pastoral simplicity, on the green turf. [Rev. Robert Forby, "Vocabulary of East Anglia," London, 1830]
lengthy (adj.): "having length" (especially "immoderately long"), 1759, American English, from length + -y (2). Until c. 1840 always characterized in British English as an Americanism.
This word has been very common among us, both in writing and in the language of conversation; but it has been so much ridiculed by Americans as well as Englishmen, that in writing it is now generally avoided. Mr. Webster has admitted it into his dictionary; but as need hardly be remarked it is not in any of the English ones. It is applied by us, as Mr. Webster justly observes, chiefly to writings or discourses. Thus we say, a lengthy pamphlet, a lengthy sermon, &c. The English would say, a long or (in the more familiar style) a longish sermon. [John Pickering, "A Vocabulary, or Collection of Words and Phrases Which Have Been Supposed to be Peculiar to the United States of America," Boston, 1816]
Related: Lengthily; lengthiness.
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."
caucus (n.): "private meeting of party leaders," 1763, American English (New England), perhaps from an Algonquian word caucauasu "counselor, elder, adviser" in the dialect of Virginia, or from the Caucus Club of Boston, a 1760s social & political club whose name possibly derived from Modern Greek kaukos "drinking cup." Another old guess is caulker's (meeting) [Pickering, 1816], but OED finds this dismissable.
CAUCUS. This noun is used throughout the United States, as a cant term for those meetings, which are held by the different political parties, for the purpose of agreeing upon candidates for office, or concerting any measure, which they intend to carry at the subsequent public, or town meetings. [John Pickering, "A Vocabulary, or Collection of Words and Phrases Which Have Been Supposed to be Peculiar to the United States of America," Boston, 1816]

The word caucus, and its derivative caucusing, are often used in Boston. The last answers much to what we stile parliamenteering or electioneering. All my repeated applications to different gentlemen have not furnished me with a satisfactory account of the origin of caucus. It seems to mean, a number of persons, whether more or less, met together to consult upon adopting and prosecuting some scheme of policy, for carrying a favorite point. [William Gordon, "History, Rise, Progress, and Establishment of the Independence of the United States of America," London, 1788]
son of a bitch: 1707 as a direct phrase, but implied much earlier, and Old Norse had bikkju-sonr. Abbreviated form SOB from 1918; form sumbitch attested in writing by 1969.
Abide þou þef malicious!
Biche-sone þou drawest amis
þou schalt abigge it ywis!
["Of Arthour & of Merlin," c. 1330]
"Probably the most common American vulgarity from about the middle of the eighteenth century to the middle of the twentieth" [Rawson].
Our maid-of-all-work in that department [indecency] is son-of-a-bitch, which seems as pale and ineffectual to a Slav or a Latin as fudge does to us. There is simply no lift in it, no shock, no sis-boom-ah. The dumbest policeman in Palermo thinks of a dozen better ones between breakfast and the noon whistle. [H.L. Mencken, "The American Language," 4th ed., 1936, p.317-8]
Elsewhere, complaining of the tepidity of the American vocabulary of profanity, Mencken writes that the toned-down form son-of-a-gun "is so lacking in punch that the Italians among us have borrowed it as a satirical name for an American: la sanemagogna is what they call him, and by it they indicate their contempt for his backwardness in the art that is one of their great glories."
It was in 1934 also that the New York Daily News, with commendable frankness, in reporting a hearing in Washington at which Senator Huey P. Long featured, forsook the old-time dashes and abbreviations and printed the complete epithet "son of a bitch." [Stanley Walker, "City Editor," 1934]
oe: found in Greek borrowings into Latin, representing Greek -oi-. Words with -oe- that came early into English from Old French or Medieval Latin usually already had been levelled to -e- (economic, penal, cemetery), but later borrowings directly from Latin or Greek tended to retain it at first (oestrus, diarrhoea, amoeba) as did proper names (Oedipus, Phoebe, Phoenix) and purely technical terms. British English tends to be more conservative with it than American, which has done away with it in all but a few instances.

It also occurred in some native Latin words (foedus "treaty, league," foetere "to stink," hence occasionally in English foetid, foederal, which was the form in the original publications of the "Federalist" papers). In these it represents an ancient -oi- in Old Latin (for example Old Latin oino, Classical Latin unus), which apparently passed through an -oe- form before being leveled out but was preserved into Classical Latin in certain words, especially those belonging to the realms of law (such as foedus) and religion, which, along with the vocabulary of sailors, are the most conservative branches of any language in any time, through a need for precision, immediate comprehension, demonstration of learning, or superstition. But in foetus it was an unetymological spelling in Latin that was picked up in English and formed the predominant spelling of fetus into the early 20c.
slang (n.): 1756, "special vocabulary of tramps or thieves," later "jargon of a particular profession" (1801), of uncertain origin, the usual guess being that it is from a Scandinavian source, such as Norwegian slengenamn "nickname," slengja kjeften "to abuse with words," literally "to sling the jaw," related to Old Norse slyngva "to sling." But OED, while admitting "some approximation in sense," discounts this connection based on "date and early associations." Liberman also denies it, as well as any connection with French langue (or language or lingo). Rather, he derives it elaborately from an old slang word meaning "narrow piece of land," itself of obscure origin. Century Dictionary says "there is no evidence to establish a Gipsy origin." Sense of "very informal language characterized by vividness and novelty" first recorded 1818.
[S]lang is a conscious offence against some conventional standard of propriety. A mere vulgarism is not slang, except when it is purposely adopted, and acquires an artificial currency, among some class of persons to whom it is not native. The other distinctive feature of slang is that it is neither part of the ordinary language, nor an attempt to supply its deficiencies. The slang word is a deliberate substitute for a word of the vernacular, just as the characters of a cipher are substitutes for the letters of the alphabet, or as a nickname is a substitute for a personal name. [Henry Bradley, from "Slang," in "Encyclopedia Britannica," 11th ed.]
A word that ought to have survived is slangwhanger (1807, American English) "noisy or abusive talker or writer."
kaput (adj.): "finished, worn out, dead," 1895 as a German word in English, from German kaputt "destroyed, ruined, lost" (1640s), which in this sense probably is a misunderstanding of an expression from card-playing, capot machen, a partial translation into German of French faire capot, a phrase which meant "to win all the tricks (from the other player) in piquet," an obsolete card game.

The French phrase means "to make a bonnet," and perhaps the notion is throwing a hood over the other player, but faire capot also meant in French marine jargon "to overset in a squall when under sail." The German word was popularized in English during World War I.
"Kaput" -- a slang word in common use which corresponds roughly to the English "done in," the French "fichu." Everything enemy was "kaput" in the early days of German victories. [F. Britten Austin, "According to Orders," New York, 1919]
French capot is literally "cover, bonnet," also the name of a type of greatcloak worn by sailors and soldiers (see capote).

The card-playing sense is attested in German only from 1690s, but capot in the (presumably) transferred sense of "destroyed, ruined, lost" is attested from 1640s (see William Jervis Jones, "A Lexicon of French Borrowings in the German Vocabulary (1575-1648)," Berlin, de Gruyter, 1976). In Hoyle and other English gaming sources, faire capot is "to win all the tricks," and a different phrase, être capot, literally "to be a bonnet," is sometimes cited as the term for losing them. The sense reversal in German might have come about because if someone wins all the tricks the other player has to lose them, and the same word capot, when it entered English from French in the mid-17c. meant "to score a capot against; to win all the tricks from," with figurative extensions, e.g.:
"There are others, says a third, that have played with my Lady Lurewell at picquet besides my lord; I have capotted her myself two or three times in an evening." [George Farquhar (1677-1707), "Sir Harry Wildair"]
filibuster (n.): 1580s, flibutor "pirate," especially, in history, "West Indian buccaneer of the 17th century" (mainly French, Dutch, and English adventurers), probably ultimately from Dutch vrijbueter (now vrijbuiter) "freebooter," a word which was used of pirates in the West Indies in Spanish (filibustero) and French (flibustier, earlier fribustier) forms. See freebooter.

According to Century Dictionary, the spread of the word is owing to a Dutch work ("De Americaensche Zee-Roovers," 1678) "written by a bucaneer named John Oexmelin, otherwise Exquemelin or Esquemeling, and translated into French and Spanish, and subsequently into English (1684)." Spanish inserted the -i- in the first syllable; French is responsible for the -s-, inserted but not originally pronounced, "a common fact in 17th century F[rench], after the analogy of words in which an original s was retained in spelling, though it had become silent in pronunciation" [Century Dictionary].

In American English, from 1851 in reference to lawless military adventurers from the U.S. who tried to overthrow Central American governments. The major expeditions were those of Narciso Lopez of New Orleans against Cuba (1850-51) and by William Walker of California against the Mexican state of Sonora (1853-54) and against Nicaragua (1855-58).
FILIBUSTERING is a term lately imported from the Spanish, yet destined, it would seem, to occupy an important place in our vocabulary. In its etymological import it is nearly synonymous with piracy. It is commonly employed, however, to denote an idea peculiar to the modern progress, and which may be defined as the right and practice of private war, or the claim of individuals to engage in foreign hostilities aside from, and even in opposition to the government with which they are in political membership. ["Harper's New Monthly Magazine," January 1853]
The noun in the legislative sense is not in Bartlett (1859) and seems not to have been in use in U.S. legislative writing before 1865 (filibustering in this sense is from 1861). Probably the extension in sense is because obstructionist legislators "pirated" debate or overthrew the usual order of authority. Originally of the senator who led it; the maneuver itself so called by 1893. Not technically restricted to U.S. Senate, but that's where the strategy works best. [The 1853 use of filibustering by U.S. Rep. Albert G. Brown of Mississippi reported in the "Congressional Globe" and cited in the OED does not refer to legislative obstruction, merely to national policy toward Cuba.]
fundamentalist (adj.): 1920 in the religious sense, from fundamental + -ist. Coined in American English to name a movement among Protestants c. 1920-25 based on scriptural inerrancy, etc., and associated with William Jennings Bryan, among others. The original notion might have been of "fundamental truths."
Fundamentalism is a protest against that rationalistic interpretation of Christianity which seeks to discredit supernaturalism. This rationalism, when full grown, scorns the miracles of the Old Testament, sets aside the virgin birth of our Lord as a thing unbelievable, laughs at the credulity of those who accept many of the New Testament miracles, reduces the resurrection of our Lord to the fact that death did not end his existence, and sweeps away the promises of his second coming as an idle dream. It matters not by what name these modernists are known. The simple fact is that, in robbing Christianity of its supernatural content, they are undermining the very foundations of our holy religion. They boast that they are strengthening the foundations and making Christianity more rational and more acceptable to thoughtful people. Christianity is rooted and grounded in supernaturalism, and when robbed of supernaturalism it ceases to be a religion and becomes an exalted system of ethics. [Curtis Lee Laws, "Herald & Presbyter," July 19, 1922]
Fundamentalist is said (by George McCready Price) to have been first used in print by Curtis Lee Laws (1868-1946), editor of "The Watchman Examiner," a Baptist newspaper. The movement may have roots in the Presbyterian General Assembly of 1910, which drew up a list of five defining qualities of "true believers" which other evangelicals published in a mass-circulation series of books called "The Fundamentals." A World's Christian Fundamentals Association was founded in 1918. The words reached widespread use in the wake of the contentious Northern Baptist Convention of 1922 in Indianapolis. In denominational use, fundamentalist was opposed to modernist. Applied to other religions since 1956 (earliest extension is to the Muslim Brotherhood).
A new word has been coined into our vocabulary -- two new words -- 'Fundamentalist' and 'Fundamentalism.' They are not in the dictionaries as yet -- unless in the very latest editions. But they are on everyone's tongue. [Address Delivered at the Opening of the Seminary, Sept. 20, 1922, by Professor Harry Lathrop Reed, "Auburn Seminary Record"]
