aspheterism (n.)
doctrine that there ought to be no private property, 1794, from Greek a- "not, without" (see a- (3)) + spheteros "one's own," from sphetrisomos "appropriation."
asphodel (n.)
late 14c., from Latin asphodelus, from Greek asphodelos, also sphodelos, spodelos, "asphodel, king's spear, plant of the lily kind," which is of unknown origin; "A substrate word, as is shown by the variants" [Beekes]. Compare daffodil. It was the peculiar plant of the dead; and in Greek mythology and English poetic use it overspreads the Elysian meadows.
To embathe In nectared lavers strewed with asphodel. [Milton, "Comus," 1634]
asphyxia (n.)
1706, "stoppage of pulse, absence of pulse," from Modern Latin asphyxia "stopping of the pulse," from Greek asphyxia "stopping of the pulse," from a- "not" (see a- (3)) + sphyzein "to throb, to beat violently," which is of unknown origin.

Obsolete in its original sense; the transferred sense of "suffocation, extreme condition caused by lack of oxygen in the blood" is from 1778, but it is a "curious infelicity of etymology" [OED] because victims of suffocation have a pulse for some time after breathing has stopped. Formerly sometimes nativized as asphyxy. Related: Asphyctic; asphyxial.
asphyxiate (v.)
1818, "to suffocate" (someone or something), "produce asphyxia," from asphyxia in its transferred sense + -ate (2). Related: Asphyxiated; asphyxiating.
asphyxiation (n.)
"act of causing asphyxia," 1849, noun of action from asphyxiate (v.).
aspic (n.)
type of savory meat jelly, 1789, from French aspic "jelly" (18c.), apparently from Old French aspe "asp" (see asp). The foodstuff said to be so called from its coldness (froid comme un aspic is said by Littré to be a proverbial phrase), or the colors in the gelatin, or the shape of the mold. It also was a French word for "lavender spike" and might refer to lavender as a seasoning element in the jelly.
aspirant (n.)
"one who aspires, one who seeks advancement," 1738, from French aspirant "a candidate," noun use of a present participle, from Latin aspirantem (nominative aspirans), present participle of aspirare "breathe at, blow upon," figuratively strive for, aspire to" (see aspire).
aspirate (n.)
1725, "a sound of or resembling or involving the letter 'H'," especially at the beginning of a word, from Latin aspirationem (nominative aspiratio) "a breathing, exhalation; the pronunciation of the letter H," from aspirare (see aspire).
aspirate (v.)
"to pronounce with audible breath," 1660s (implied in aspirated); perhaps a back-formation from aspiration (n.2), or from French aspirer or directly from Latin aspiratus, past participle of aspirare "breathe at, blow upon" (see aspire). Related: Aspirating.
aspiration (n.1)
1530s, "action of breathing into," from Latin aspirationem (nominative aspiratio) "a breathing on, a blowing upon; rough breathing; influence," noun of action from past participle stem of aspirare "strive for, seek to reach," literally "breathe at, blow upon" (see aspire). Meaning "steadfast longing for a higher goal, earnest desire for something above one" is recorded from c. 1600 (sometimes collectively, as aspirations).
aspiration (n.2)
late 14c., "action of aspirating, a spirant letter or sound," noun of action from aspirate (v.).
aspirational (adj.)
"characterized by steadfast desire for a higher position," 1860, from aspiration (n.1) + -al (1). Earlier adjectives were aspirant "aspiring, ambitious" (1814); aspiring "animated by ardent desire" (1570s).
aspirator (n.)
"apparatus for drawing air or gas through a tube," 1863, agent noun from Latin aspirare (see aspire (v.)).
aspire (v.)
"strive for, seek eagerly to attain, long to reach," c. 1400, from Old French aspirer "aspire to; inspire; breathe, breathe on" (12c.), from Latin aspirare "to breathe upon, blow upon, to breathe," also, in transferred senses, "to be favorable to, assist; to climb up to, to endeavor to obtain, to reach to, to seek to reach; infuse," from ad "to" (see ad-) + spirare "to breathe" (see spirit (n.)). The notion is of "panting with desire," or perhaps of rising smoke. Literal sense of "breathe, exhale" (1530s) is rare in English. Related: Aspired; aspiring.
aspirin (n.)
coined 1899 by German chemist Heinrich Dreser (1860-1924) in German as a trademark name, from Latin Spiraea (ulmaria) "meadow-sweet," the plant in whose flowers or leaves the processed acid in the medicine is naturally found, + common chemical ending -in (see -ine (2)). Spiraea (Tournefort, 1700) is from Latinized form of Greek speiraia "meadow-sweet," so called from the shape of its follicles (see spiral (adj.)). The initial -a- is to acknowledge acetylation; Dreser said the word was a contraction of acetylierte spirsäure, the German name of the acid, which now is obsolete, replaced by salicylic acid.
Die Bezeichnung Aspirin ist abgeleitet aus "Spirsäure" -- alter Name der Salicylsäure und A = Acetyl; statt: Acetylirte Spirsäure, kurzweg "Aspirin". [H, Dreser, "Pharmakologisches über Aspirin (Acetylsalicylsäure)," in "Archiv für die Gesammte Physiologie des Menschen und der Thiere," 1899, p.307]
The custom of giving commercial names to medicinal products began in Germany in the late 19th century, when nascent pharmaceutical firms were discovering medical uses for common, easily made chemicals. To discourage competitors they would market the substance under a short trademarked name a doctor could remember, rather than the long chemical compound word. German law required prescriptions to be filled exactly as written.
asportation (n.)
"a carrying away or off" (legal), c. 1500, from Latin asportationem (nominative asportatio) "a carrying away," noun of action from past participle stem of asportare "to carry off," from abs- "away" (see ab-) + portare "to carry" (from PIE root *per- (2) "to lead, pass over").
asquat (adj.)
1748, from a- (1) "on" + squat (n.).
asquint (adv.)
early 13c., "obliquely, with a sidelong glance," of uncertain etymology; from a- (1) "on" + "a word corresponding to Du. schuinte 'slope, slant' of the independent use of which no instances survive ..." [OED]. "Middle English Dictionary" compares French équinter "cut to a point;" French dialectal (e)squintar "cast a glance, look furtively." Squint is not found in Middle English, and appears to be from this word.
ass (n.1)
solid ungulate quadruped beast of burden of the horse kind, but smaller and with long ears and a short mane, native to southwest Asia, Old English assa (Old Northumbrian assal, assald) "he-ass." The English word is cognate with Old Saxon esil, Dutch ezel, Old High German esil, German Esel, Gothic asilus, and, beyond Germanic, Lithuanian asilas, Old Church Slavonic osl, Russian oselŭ, etc. All probably are ultimately from Latin asinus. De Vaan says the form of asinus suggests it was a loan-word into Latin, and adds, "Most IE words for 'ass' are loanwords."

Together with Greek onos it is conjectured to be from a language of Asia Minor (compare Sumerian ansu). The initial vowel of the English word might be by influence of Celtic forms (Irish and Gaelic asal), from Old Celtic *as(s)in "donkey." In Romanic tongues the Latin word has become Italian asino, Spanish asno, Old French asne, French âne.
In familiar use, the name ass is now to a great extent superseded by donkey (in Scotland cuddie); but ass is always used in the language of Scripture, Natural History, proverb, and fable; also, in ordinary use, in Ireland. [OED]
Sure-footed and patient in domestication, since ancient Greek times, in fables and parables, the animal has typified clumsiness and stupidity (hence ass-head, late 15c., etc.). To make an ass of oneself is from "A Midsummer Night's Dream" (1590). Asses' Bridge (c. 1780), from Latin Pons Asinorum, is fifth proposition of first book of Euclid's "Elements." In Middle English, someone uncomprehending or unappreciative would be lik an asse that listeth on a harpe. In 15c., an ass man was a donkey-driver.
For al schal deie and al schal passe, Als wel a Leoun as an asse. [John Gower, "Confessio Amantis," 1393]
ass (n.2)
slang for "backside," first attested 1860 in nautical slang, in popular use from 1930; chiefly U.S.; from dialectal variant pronunciation of arse (q.v.). The loss of -r- before -s- is attested in other words (burst/bust, curse/cuss, horse/hoss, barse/bass, garsh/gash). Indirect evidence of the change from arse to ass can be traced to 1785 (in euphemistic avoidance of ass "donkey" by polite speakers) and perhaps to Shakespeare, if Nick Bottom transformed into a donkey in "A Midsummer Night's Dream" (1594) is the word-play some think it is.
I must to the barber's, mounsieur; for me thinks I am marvellous hairy about the face; and I am such a tender ass, if my hair do but tickle me, I must scratch. [Bottom]
Meaning "woman regarded as a sexual object" is from 1942 (piece of ass), but the image is older (compare buttock "a common strumpet," 1670s). To have (one's) head up (one's) ass "not know what one is doing" is attested by 1969. Colloquial (one's) ass "one's self, one's person" attested by 1958. To work (one's) ass off "work very much" is by 1946; to laugh (one's) ass off "laugh very much" is by 1972 (implied from 1965). Ass-kissing (adj.) "currying favor" is by 1974.

Earlier the word was a Northern English and Scottish dialectal variant of ash-hole "receptacle for ashes beneath a grate." Wright's "English Dialect Dictionary" (1898) lists many examples, such as, "Tell'd her a hunderd times nivver to put t'poaker i' t'ass-hoil" [West Yorkshire].
assail (v.)
"attack violently," c. 1200, from Old French assalir "attack, assault, assail" (12c., Modern French assaillir), from Vulgar Latin *adsalire "to leap at," from Latin ad "to, toward" (see ad-) + salire "to leap" (see salient (adj.)).

Perhaps the most interesting department in the whole factory, to the visitor, is the final assembly. In this division, all the assembled units meet the assembly conveyor at the point where they are needed. At the start of the track a front axle unit, a rear axle unit and a frame unit are assembled. This assembly is then started in motion by means of a chain conveyor, and as it moves down the room at a constant speed of eight feet per minute, each man adds one part to the growing chassis or does one operation, which is assigned to him, so that when the chassis reaches the end of the line, it is ready to run on its own power.
