c. 1300, gyrle "child, young person" (of either sex but most frequently of females), of unknown origin. One guess [OED] leans toward an unrecorded Old English *gyrele, from Proto-Germanic *gurwilon-, diminutive of *gurwjoz (apparently also represented by Low German gære "boy, girl," Norwegian dialectal gorre, Swedish dialectal gurre "small child," though the exact relationship, if any, between all these is obscure), from PIE *ghwrgh-, also found in Greek parthenos "virgin." But this involves some objectionable philology. Liberman (2008) writes:
Girl does not go back to any Old English or Old Germanic form. It is part of a large group of Germanic words whose root begins with a g or k and ends in r. The final consonant in girl is a diminutive suffix. The g-r words denote young animals, children, and all kinds of creatures considered immature, worthless, or past their prime.
Another candidate is Old English gierela "garment" (for possible sense evolution in this theory, compare brat). A former folk-etymology derivation from Latin garrulus "chattering, talkative" is now discarded. Like boy, lass, lad it is of more or less obscure origin. "Probably most of them arose as jocular transferred uses of words that had originally different meaning" [OED]. Specific meaning of "female child" is late 14c. Applied to "any young unmarried woman" since mid-15c. Meaning "sweetheart" is from 1640s. Old girl in reference to a woman of any age is recorded from 1826. Girl next door as a type of unflashy attractiveness is recorded by 1953 (the title of a 20th Century Fox film starring June Haver).
Doris [Day] was a big vocalist even before she hit the movies in 1948. There, as the latest movie colony "girl next door," sunny-faced Doris soon became a leading movie attraction as well as the world's top female recording star. "She's the girl next door, all right," said one Hollywood admirer. "Next door to the bank." [Life magazine, Dec. 22, 1958]
Girl Friday "resourceful young woman assistant" is from 1940, a reference to "Robinson Crusoe." Girl Scout is from 1909. For the usual Old English word, see maiden.
c. 1600, "shield louse (Coccus ilicis) that yields a red dye" (1590s of the tree on which the insects live), from Medieval Latin cremesinus (also source of French kermès, Italian chermes, Spanish carmes), from Arabic qirmiz "kermes," from Sanskrit krmi-ja a compound meaning "(red dye) produced by a worm."
The Sanskrit compound is krmih "worm" (from PIE root *kwrmi- "worm," source also of Lithuanian kirmis, Old Irish cruim, Albanian krimp "worm") + -ja- "produced" (from PIE root *gene- "give birth, beget"). The insect lives in the Levant and southern Europe on a species of small evergreen oak (kermes oak) and in ancient Europe were the main source of red and scarlet dye. The dye is prepared from the dried bodies of pregnant females, which alive resemble small roundish grains about the size of peas and cling immobile to the tree on which they live. From this fact kermes dye was, for a long time, mistaken as being from a seed or excrescence of the tree, and the word for it in Greek was kokkos, literally "a grain, seed" (see cocco-). This was passed to Latin as coccum, coccus "berry [sic] yielding scarlet dye," in late use "scarlet color, scarlet garment."
So important was kermes (coccus) as a commercial source of scarlet dye that derivatives of the name for it have displaced the original word for "red" in many languages, such as Welsh coch (from Latin), Modern Greek kokkinos. Also compare Russian čcermnyj "purple-red," Old Church Slavonic čruminu. Compare also crimson (n.).
Kermes dyes have been found in burial wrappings in Anglo-Scandinavian York, but the use of kermes dyes seems to have been lost in Europe from the Dark Ages until early 15c. It fell out of use again with the introduction of cochineal (the word for which itself might be from coccus) from the New World.
Cloths dyed with kermes are of a deep red colour; and though much inferior in brilliancy to the scarlet cloths dyed with real Mexican cochineal, they retain the colour better and are less liable to stain. The tapestries of Brussels and other parts of Flanders, which have scarcely lost any thing of their original brilliancy, even after a lapse of 200 years, were all dyed with kermes. [W.T. Brande, "Dictionary of Science, Literature, & Art," London, 1842]
A sound found chiefly in words of Old English, Old Norse or Greek origin, unpronounceable by Normans and many other Europeans. In Greek, the sound corresponds etymologically to Sanskrit -dh- and English -d-; and it was represented graphically by -TH- and at first pronounced as a true aspirate (as still in English outhouse, shithead, etc.).
But by 2c. B.C.E. the Greek letter theta was in universal use and had the modern "-th-" sound. Latin had neither the letter nor the sound, however, and the Romans represented Greek theta by -TH-, which they generally pronounced, at least in Late Latin, as simple "-t-" (passed down to Romanic languages, as in Spanish termal "thermal," teoria "theory," teatro "theater").
In Germanic languages it represents PIE *-t- and was common at the start of words or after stressed vowels. To represent it, Old English and Old Norse used the characters ð "eth" (a modified form of -d-) and þ "thorn," which originally was a rune. Old English, unlike Old Norse, seems never to have standardized which of the two versions of the sound ("hard" and "soft") was represented by which of the two letters.
The digraph -th- sometimes appears in early Old English, on the Roman model, and it returned in Middle English with the French scribes, driving out eth by c. 1250, but thorn persisted, especially in demonstratives (þat, þe, þis, etc.), even as other words were being spelled with -th-. The advent of printing dealt its death-blow, however, as types were imported from continental founders, who had no thorn. For a time y was used in its place (especially in Scotland), because it had a similar shape, hence ye for the in historical tourist trap Ye Olde _______ Shoppe (it never was pronounced "ye," only spelled that way).
The awareness that some Latin words in t- were from Greek th- encouraged over-correction in English and created unetymological forms such as Thames and author, while some words borrowed from Romanic languages preserve, on the Roman model, the Greek -th- spelling but the simple Latin "t" pronunciation (as in Thomas and thyme).
third letter of the alphabet. Alphabetic writing came to Rome via the southern Etruscan "Caeretan" script, in which gamma was written as a crescent. Early Romans made little use of Greek kappa and used gamma for both the "g" and "k" sounds, the latter more frequently, so that the "k" sound came to be seen as the proper one for gamma. Classical Latin -c-, with only the value "k," passed to Celtic and, via missionary Irish monks, to the Anglo-Saxons. Also see cee.
In some Old English words, before some vowels and in certain positions, -c- had a "ts" sound that was respelled ch- in Middle English by French scribes (chest, cheese, church; see ch). In Old English -k- was known but little used.
Meanwhile, in Old French, many "k" sounds drifted to "ts" and by 13c., "s," but still were written -c-. Thus the 1066 invasion brought to the English language a flood of French and Latin words in which -c- represented "s" (as in cease, ceiling, circle) and a more vigorous use of -k- to distinguish that sound. By 15c. even native English words with -s- were being respelled with -c- for "s" (ice, mice, lice).
In some English words from Italian, the -c- has a "ch" sound (via a sound evolution somewhat like the Old French one). In German, -c- in loanwords was regularized to -k- or -z- (depending on pronunciation) in the international spelling reform of 1901, which was based on the Duden guide of 1880.
As a symbol in the Roman numeral system, "one hundred;" the symbol originally was a Greek theta, but was later reduced in form and understood to stand for centum. In music, it is the name of the keynote of the natural scale, though the exact pitch varied in time and place 18c. and 19c. from 240 vibrations per second to 275; it wasn't entirely regularized (at 261.63) until the adoption of the A440 standard in the 1930s. C-spring as a type of carriage spring is from 1794, so called for its shape.
eighth letter of the alphabet; it comes from Phoenician, via Greek and Latin. In Phoenician it originally had a rough guttural sound like German Reich or Scottish loch. In Greek at first it had the value of Modern English -h-, and with this value it passed into the Latin alphabet via Greek colonies in Italy. Subsequently in Greek it came to be used for a long "e" sound; the "h" sound being indicated by a fragment of the letter, which later was reduced to the aspiration mark.
In Germanic it was used for the voiceless breath sound when at the beginning of words, and in the middle or at the end of words for the rough guttural sound, which later came to be written -gh.
The sound became totally silent in Vulgar Latin and in the languages that emerged from it; thus the letter was omitted in Old French and Italian, but it was restored pedantically in French and Middle English spelling, and often later in English pronunciation. Thus Modern English has words ultimately from Latin with missing -h- (able, from Latin habile); with a silent -h- (heir, hour); with a formerly silent -h- now often vocalized (humble, humor, herb); and even a few with an unetymological -h- fitted in confusion to words that never had one (hostage, hermit). Relics of the formerly unvoiced -h- persist in pedantic insistence on an historical (object) and in obsolete mine host.
The pronunciation "aitch" was in Old French (ache "name of the letter H"), and is from a presumed Late Latin *accha (compare Italian effe, elle, emme), with the central sound approximating the rough, guttural value of the letter in Germanic. In earlier Latin the letter was called ha. The use in digraphs (as in -sh-, -th-) goes back to the ancient Greek alphabet, which used it in -ph-, -th-, -kh- until -H- took on the value of a long "e" and the digraphs acquired their own characters. The letter passed into Roman use before this evolution, and thus retained there more of its original Semitic value.
Old English hyll "hill," from Proto-Germanic *hulni- (source also of Middle Dutch hille, Low German hull "hill," Old Norse hallr "stone," Gothic hallus "rock," Old Norse holmr "islet in a bay," Old English holm "rising land, island"), from PIE root *kel- (2) "to be prominent; hill." Formerly including mountains.
In Great Britain heights under 2,000 feet are generally called hills; 'mountain' being confined to the greater elevations of the Lake District, of North Wales, and of the Scottish Highlands; but, in India, ranges of 5,000 and even 10,000 feet are commonly called 'hills,' in contrast with the Himalaya Mountains, many peaks of which rise beyond 20,000 feet. [OED]
The term mountain is very loosely used. It commonly means any unusual elevation. In New England and central New York, elevations of from one to two thousand feet are called hills, but on the plains of Texas, a hill of a few hundred feet is called a mountain. [Ralph S. Tarr, "Elementary Geology," Macmillan, 1903]
Despite the differences in defining mountain systems, Penck (1896), Supan (1911) and Obst (1914) agreed that the distinction between hills, mountains, and mountain systems according to areal extent or height is not a suitable classification. ["Geographic Information Science and Mountain Geomorphology," 2004]
Figurative phrase over the hill "past one's prime" is recorded by 1950. Expression old as the hills is recorded by 1819, perhaps echoing Job xv.7. Earlier form old as the hills and the valleys is attested by 1808:
And this is no "new morality." It is morality as old as the hills and the valleys. It is a morality which must be adopted; or, we must confess that there are certain political evils greater than that of seeing one's country conquered. [Cobbett's Weekly Political Register, Feb. 6, 1808]
Cobbett's also had, on April 11, 1818:
However, thus it always is: "those whom God intends to destroy, he first makes foolish," which is a saying as old as the hills between Everly and Marlborough.
"the Scriptures of the Old and New Testaments," early 14c., from Anglo-Latin biblia, Old French bible (13c.) "the Bible," also any large book generally, from Medieval and Late Latin biblia "the Bible" (neuter plural interpreted as feminine singular), from phrase biblia sacra "holy books," a translation of Greek ta biblia to hagia "the holy books." The Latin word is from the Greek one, biblion "paper, scroll," also the ordinary word for "a book as a division of a larger work;" see biblio-.
The Christian scripture was referred to in Greek as Ta Biblia as early as c. 223. Bible replaced Old English biblioðece (see bibliothec) as the ordinary word for "the Scriptures." Figurative sense of "any authoritative book" is from 1804. Bible-thumper "strict Christian" is from 1870. Bible belt in reference to the swath of the U.S. South then dominated by fundamentalist Christians is from 1926; likely coined by H.L. Mencken.
Her first husband was a missionary to China, and died miserably out there, leaving her with a small baby and no funds. Her second seems to have left her nearly as quickly, though under his own steam: her souvenir was another infant. For years she toured the Bible Belt in a Ford, haranguing the morons nightly under canvas. [H.L. Mencken, review of Aimee Semple McPherson's "In the Service of the King: The Story of My Life," The American Mercury, April 1928]
Walter Scott and Pope's Homer were reading of my own election, but my mother forced me, by steady daily toil, to learn long chapters of the Bible by heart; as well as to read it every syllable through, aloud, hard names and all, from Genesis to the Apocalypse, about once a year; and to that discipline — patient, accurate, and resolute — I owe, not only a knowledge of the book, which I find occasionally serviceable, but much of my general power of taking pains, and the best part of my taste in literature. ... [O]nce knowing the 32nd of Deuteronomy, the 119th Psalm, the 15th of 1st Corinthians, the Sermon on the Mount, and most of the Apocalypse, every syllable by heart, and having always a way of thinking with myself what words meant, it was not possible for me, even in the foolishest times of youth, to write entirely superficial or formal English .... [John Ruskin, "Fors Clavigera," 1871]
fourteenth letter of the English alphabet; in chemistry, the symbol for nitrogen.
In late Middle English a and an commonly were joined to the following noun, if that word began with a vowel, which caused confusion over how such words ought to be divided when written separately. In nickname, newt, and British dialectal naunt, the -n- belongs to a preceding indefinite article an or possessive pronoun mine.
Other examples of this from Middle English manuscripts include a neilond ("an island," early 13c.), a narawe ("an arrow," c. 1400), a nox ("an ox," c. 1400), a noke ("an oak," early 15c.), a nappyle ("an apple," early 15c.), a negge ("an egg," 15c.), a nynche ("an inch," c. 1400), a nostryche ("an ostrich," c. 1500). A manuscript from c. 1500 has a nylle for "an isle." My naunt for mine aunt is recorded from 13c.-17c. None other could be no noder (mid-15c.). My nown (for mine own) was frequent 15c.-18c. In 16c., an idiot sometimes became a nidiot (1530s), which, with still-common casual pronunciation, became nidget (1570s), which, alas, has not survived. Also compare nonce, pigsney. Even in 19c. provincial English and U.S., noration (from an oration) was "a speech; a rumor."
The process also worked in surnames, from oblique cases of Old English at "by, near," as in Nock/Nokes/Noaks from atten Oke "by the oak;" Nye from atten ye "near the lowland;" and see Nashville. (Elision of the vowel of the definite article also took place and was standard in Chancery English of the 15c.: þarchebisshop for "the archbishop," thorient for "the orient.")
But it is more common for an English word to lose an -n- to a preceding a: apron, auger, adder, umpire, humble pie, etc. By a related error in Elizabethan English, natomy or atomy was common for anatomy, noyance (annoyance) and noying (adj.) turn up 14c.-17c., and Marlowe (1590) has Natolian for Anatolian. The tendency is not limited to English: compare Luxor, jade (n.1), lute, omelet, and Modern Greek mera for hēmera, the first syllable being confused with the article.
The mathematical use of n for "an indefinite number" is attested by 1717 in phrases such as to the nth power (see nth). In Middle English n. was written in form documents to indicate an unspecified name of a person to be supplied by the speaker or reader.
popular name of a common bird of Europe, Asia, and America, known for its chattering, acquisitiveness, curiosity, and mimicry, c. 1600, earlier simply pie (mid-13c.).
The first element is Mag, nickname for Margaret, long used in proverbial and slang English for qualities associated generally with women, especially in this case "idle chattering" (as in Magge tales "tall tales, nonsense," early 15c.; also compare French margot "magpie," from Margot, pet form of Marguerite). The name Margaret, and its reduced forms Mag, Madge, diminutive Maggie, also has long been familiarly applied to birds. Pies were proverbial since Middle English for chattering (as were jays), hence the application of pie to a prattling gossip or tattler, also "sly person, informer" (late 14c.) and in 15c.-16c. a wily pie (or wyly pye) was "a cunning person."
The second element, pie, is the earlier name of the bird, from Old French pie, from Latin pica "magpie" (source also of Spanish pega), fem. of picus "woodpecker," from PIE root *(s)peik- "woodpecker, magpie" (source also of Umbrian peica "magpie," Sanskrit pikah "Indian cuckoo," Old Norse spætr, German Specht "woodpecker"); possibly from PIE root *pi-, denoting pointedness, of the beak. The application to pies might be because the magpie also has a long, pointed tail.
The birds are proverbial for pilfering and hoarding and for their indiscriminate appetites (see pica (n.2)); they can be taught to speak, and have been regarded since the Middle Ages as ill omens.
Whan pyes chatter vpon a house it is a sygne of ryghte euyll tydynges. 
Divination by numbering magpies is attested from c. 1780 in Lincolnshire; the rhyme varies from place to place, the only consistency being that one is bad, two are good.
The councils which magpies appear to hold together, at particular seasons, commonly called "folkmotes," are associated in the minds of many with superstitious and ominous notions. The innocent objects of terror, while meeting together most probably for the purpose of choosing mates, are supposed to be conspiring and clubbing their wits, for the weal or woe of the inhabitants of the neighbouring village. If they are of an even number and carry on their cheerful, noisy chatter, it is supposed to betoken good to old and young—but if there is an odd magpie perched apart from the rest, silent, and disconsolate, the reverse of this is apprehended, and mischievous consequences are inevitably expected. [The Saturday Magazine, Jan. 23, 1841]
1507, "the western hemisphere, North and South America," in Cartographer Martin Waldseemüller's treatise "Cosmographiae Introductio," from Modern Latin Americanus, after Amerigo Vespucci (1454-1512) who made two trips to the New World as a navigator and claimed to have discovered it. His published works put forward the idea that it was a new continent, and he was first to call it Novus Mundus "New World." Amerigo is more easily Latinized than Vespucci (Latin Vesputius, which might have yielded place-name Vesputia). The sense in English naturally was restricted toward the British colonies, then the United States.
The man's name Amerigo is Germanic, said to derive from Gothic Amalrich, literally "work-ruler." The Old English form of the name has come down as surnames Emmerich, Emery, etc. The Italian fem. form merged into Amelia.
Colloquial pronunciation "Ameri-kay," not uncommon 19c., goes back to at least 1643 and a poem that rhymed the word with away. Amerika "U.S. society viewed as racist, fascist, oppressive, etc." is attested from 1969; the spelling is German but may also suggest the KKK.
It is a thousand pities that the puny witticisms of a few professional objectors should have the power to prevent, even for a year, the adoption of a name for our country. At present we have, clearly, none. There should be no hesitation about "Appalachia." In the first place, it is distinctive. "America" is not, and can never be made so. We may legislate as much as we please, and assume for our country whatever name we think right — but to use it will be no name, to any purpose for which a name is needed, unless we can take it away from the regions which employ it at present. South America is "America," and will insist upon remaining so. [Edgar Allan Poe, "Marginalia," in Graham's Magazine, Philadelphia, December 1846]
FREDONIA, FREDONIAN, FREDE, FREDISH, &c. &c. These extraordinary words, which have been deservedly ridiculed here as well as in England, were proposed sometime ago, and countenanced by two or three individuals, as names for the territory and people of the United States. The general term American is now commonly understood (at least in all places where the English language is spoken,) to mean an inhabitant of the United States; and is so employed, except where unusual precision of language is required. [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]
