The Medieval Latin word was held by folk-etymology to be from Arabic abu arak, literally "the father of sweat," supposedly so called by Arab physicians for its effect on humans. But OED and other sources find it rather to be from Latin borra "rough hair, short wool," in reference to the texture of the foliage. Related: Boraginaceous.
hydrocarbon radical occurring in many compounds, 1835, from French méthylène (1834), coined by Jean-Baptiste-André Dumas (1800-1884) and Eugène-Melchior Péligot (1811-1890) from Greek methy "wine" (see mead (n.1)) + hylē "wood" (which is of uncertain etymology) + Greek name-forming element -ene. So called because it was detected in wood alcohol.
"The breakdown of methylene into methyl and -ene, and the identification of the last syllable of methyl with the general suffix -yl, led to the use of meth- as a separate combining-element, as, for example, in methane, methacrylic" [Flood]. The color methylene-blue (1880) was derived from dimethylanaline.
chemical base used in making colorful dyes, 1843, coined 1841 by German chemist Carl Julius Fritzsche and adopted by Hofmann, ultimately from Portuguese anil "the indigo shrub," from Arabic an-nil "the indigo," assimilated from al-nil (with Arabic definite article al-), from Persian nila, ultimately from Sanskrit nili "indigo," from nilah "dark blue."
With suffix -ine indicating "derived substance" (see -ine (1); also see -ine (2) for the later, more precise, use of the suffix in chemistry). Discovered in 1826 in indigo and at first called crystallin; it became commercially important in 1856 when mauve dye was made from it. As an adjective from 1860.
late 14c., "pertaining to the sky or the visible heavens; pertaining to the Christian or pagan heaven," from Old French celestial "celestial, heavenly, sky-blue," from Latin caelestis "heavenly, pertaining to the sky," from caelum "heaven, sky; abode of the gods; climate," which is of uncertain origin; perhaps from PIE *kaid-slo-, perhaps from a root also found in Germanic and Baltic meaning "bright, clear" (compare Lithuanian skaidrus "shining, clear;" Old English hador, German heiter "clear, shining, cloudless," Old Norse heið "clear sky").
The Latin word is the source of the usual word for "sky" in most of the Romance languages, such as French ciel, Spanish cielo, Italian cielo, Portuguese céu. Transferred sense of "heavenly, very delightful" in English is from early 15c. Celestial Empire "China" is from 1808, translating native names.
1590s, "a disordered state, more or less temporary, of the mind, often occurring during fever or illness," from Latin delirium "madness," from deliriare "be crazy, rave," literally "go off the furrow," a plowing metaphor, from phrase de lire, from de "off, away" (see de-) + lira "furrow, earth thrown up between two furrows," from PIE root *lois- "track, furrow." Meaning "violent excitement, mad rapture" is from 1640s.
Delirium tremens (1813) is medical Latin, literally "trembling delirium," introduced 1813 by British physician Thomas Sutton for "that form of delirium which is rendered worse by bleeding, but improved by opium. By Rayer and subsequent writers it has been almost exclusively applied to delirium resulting from the abuse of alcohol" ["The New Sydenham Society's Lexicon of Medicine and the Allied Sciences," London, 1882]. As synonyms, Farmer lists barrel-fever, gallon distemper, blue Johnnies, bottle ache, pink spiders, quart-mania, snakes in the boots, triangles, uglies, etc.
"too precise, over-particular," 1895, probably Southern U.S. dialect, first attested in Joel Chandler Harris, perhaps an alteration of precise (q.v.), or a merger of prim and sissy [OED]. Related: Prissily; prissiness.
["]Then Mrs Blue Hen rumpled up her feathers and got mad with herself, and went to setting. I reckon that's what you call it. I've heard some call it 'setting' and others 'sitting.' Once, when I was courting, I spoke of a sitting hen, but the young lady said I was too prissy for anything."
"What is prissy?" asked Sweetest Susan.
Mr. Rabbit shut his eyes and scratched his ear. Then he shook his head slowly.
"It's nothing but a girl's word," remarked Mrs. Meadows by way of explanation. "It means that somebody's trying hard to show off."
"I reckon that's so," said Mr. Rabbit, opening his eyes. He appeared to be much relieved.
[Joel Chandler Harris, "Mr. Rabbit at Home"]
1590s, from star (n.) + spangle (v.); Star-Spangled Banner "United States flag" is 1814, from Francis Scott Key's poem (printed in the "Baltimore Patriot" Sept. 20), in reference to the bombardment of Fort McHenry in Baltimore overnight Sept. 13-14.
The Stars and Stripes developed from the striped flag of Boston's Sons of Liberty, and the blue and white star-spangled standards of George Washington's army. It involved the advice of a Quaker seamstress, the prompting of an American Indian, the timely intervention by Pennsylvania politicians, the inspiration of Francis Hopkinson, and a resolution of the Continental Congress.
These Americans were part of a process of mixed enterprise that combined public effort and private initiative in a way that was typical of the new republic. An American Indian was not reluctant to instruct the rulers of the Colonies on what should be done, and they were quick to respond to his suggestion. A Philadelphia seamstress did not hesitate to criticize the commander-in-chief of the Continental Army, and he was open to her advice. The Continental Congress accepted these contributions in the spirit of the open society that America was becoming. [David Hackett Fischer, "Liberty and Freedom"]
proverbial for "something extremely rare or non-existent" (late 14c.) is from Juvenal ["Sat." vi. 164], but the real thing turned up in Australia (Chenopsis atratus).
"Do you say no worthy wife is to be found among all these crowds?" Well, let her be handsome, charming, rich and fertile; let her have ancient ancestors ranged about her halls; let her be more chaste than all the dishevelled Sabine maidens who stopped the war—a prodigy as rare upon the earth as a black swan! yet who could endure a wife that possessed all perfections? I would rather have a Venusian wench for my wife than you, O Cornelia, mother of the Gracchi, if, with all your virtues, you bring me a haughty brow, and reckon up Triumphs as part of your marriage portion. [Juvenal]
Blue dahlia also was used 19c. for "something rare and unheard of."
early 15c., "of a bluish-leaden color," from Old French livide (13c.) and directly from Latin lividus "of a bluish color, black-and-blue," figuratively "envious, spiteful, malicious," from livere "be bluish," earlier *slivere, from PIE *sliwo-, suffixed form of root *sleiə- "bluish" (source also of Old Church Slavonic and Russian sliva "plum;" Lithuanian slyvas "plum;" Old Irish li, Welsh lliw "color, splendor," Old English sla "sloe").
Somehow it has come to be associated with "pale, colorless." The sense of "furiously angry" (1912) is from the notion of being livid with rage. Perhaps this is the key to the meaning shift. Rage makes some dark-red-faced; purple with rage is not uncommon in old novels (" 'My money! ye pirate! or I'll strangle you.' And he advanced upon him purple with rage, and shot out his long threatening arm, and brown fingers working in the air.") while it makes others go pale, also a figure in old novels ("At this juncture, the door opened, and, pale with rage, her eyes flashing fire, Lady Audley stood before them.")
