📘单词丨

c. 1200, o cros, "in the shape of a cross;" c. 1300, a-croiz, "in a crossed position;" early 14c., acros, "from one side to another;" a contraction of Anglo-French an cros, literally "on cross;" see a- (1) + cross (n.)).
Meaning "on the other side (as a result of crossing)" is from 1750. In crossword puzzle clues from 1924. Spelling acrost, representing a dialectal or vulgar pronunciation, is attested by 1759. Phrase across the board "embracing all categories" (1945) is said to be originally from horse-racing, in reference to a bet of the same amount of money on a horse to win, place, or show. To get (something) across "make (something) understood or appreciated" is by 1913, probably from earlier theater expression get (something) across the footlights, perform it so as to be received by the audience (1894).

📘单词丨across (adv./prep.)

"elevated part of a Greek city," often the site of original settlement and usually a citadel, 1660s, from Latinized form of Greek akropolis "citadel" (especially, with capital A-, that of Athens), from akros "highest, upper" (from PIE root *ak- "be sharp, rise (out) to a point, pierce") + polis "city" (see polis). The plural would be acropoles.

📘单词丨acropolis (n.)

"morbid fear of heights," 1887, medical Latin, from Greek akros "at the end, topmost" (from PIE root *ak- "be sharp, rise (out) to a point, pierce") + -phobia "fear." Coined by Italian physician Dr. Andrea Verga in a paper describing the condition, from which Verga himself suffered.In this paper, read somewhat over a year ago at the congress of alienists at Pavia, the author makes confession of his own extreme dread of high places. Though fearless of the contagion of cholera, he has palpitations on mounting a step-ladder, finds it unpleasant to ride on the top of a coach or to look out of even a first-story window, and has never used an elevator. [abstract of Verga's report in American Journal of Psychology, November 1888]

📘单词丨acrophobia (n.)

"one suffering from a morbid fear of heights," 1895, from acrophobia; also see -phobe. Related: Acrophobic.

📘单词丨acrophobe (n.)

word formed from the first letters of a series of words, 1943, American English coinage from acro- + -onym "name" (abstracted from homonym; ultimately from PIE root *no-men- "name"). With the exception of cabalistic esoterica and acrostic poetry, this way of forming words was exceedingly uncommon before 20c. For distinction of use (regretfully ignored on this site), see initialism.

📘单词丨acronym (n.)

"gigantism due to activity of pituitary after normal growth has ceased," 1886, from French acromégalie, from medical Latin acromegalia, from Greek akron "extremity, highest point, mountain peak, headland," neuter of akros "at the furthest point" (from PIE root *ak- "be sharp, rise (out) to a point, pierce") + megas "great" (fem. megale; from PIE root *meg- "great"). Said in contemporary literature to have been coined 1885 by French physician Dr. Pierre Marie.

📘单词丨acromegaly (n.)

"of or pertaining to an acrobat or an acrobat's performances," 1848; see acrobat + -ic, probably modeled on French acrobatique. Related: Acrobatically.

📘单词丨acrobatic (adj.)

1859, "acrobatic performances or feats," from acrobatic; also see -ics. Also acrobatism (1864). Acrobacy (1918, from French acrobatie) sometimes was used. Figurative use is attested by 1915.

📘单词丨acrobatics (n.)

1845, from French acrobate "tightrope-walker" (14c.) and directly from a Latinized form of Greek akrobatēs "rope dancer, gymnastic performer," which is related to akrobatos "going on tip-toe, climbing up high," from akros "topmost, at the point end" (from PIE root *ak- "be sharp, rise (out) to a point, pierce") + Greek agential element -batēs "one that goes, one that treads (in some manner), one that is based," from -batos, verbal adjective from stem of bainein "to go, walk, step" (from PIE root *gwa- "to go, come").

📘单词丨acrobat (n.)

word-forming element meaning "highest, topmost, at the extremities," before vowels acr-, from Latinized form of Greek akro- "pertaining to an end, extreme," from akros "at the end, at the top, outermost; consummate, excellent" (from PIE *akri-, from root *ak- "be sharp, rise (out) to a point, pierce").

📗前缀丨acro-

1540s, "quality of being sharp or pungent in taste," from French acrimonie or directly from Latin acrimonia "sharpness, pungency of taste," figuratively "acrimony, severity, energy," abstract noun from acer "sharp" (fem. acris), from PIE root *ak- "be sharp, rise (out) to a point, pierce") + -monia suffix of action, state, condition (see -mony). Figurative extension to personal sharpness or bitterness is by 1610s.

📘单词丨acrimony (n.)

1610s, "acrid," from French acrimonieux, from Medieval Latin acrimoniosus, from Latin acrimonia "sharpness" (see acrimony). Now usually figurative, of dispositions, debates, etc., "bitter, irritating in manner" (1775). Related: Acrimoniously; acrimoniousness.

📘单词丨acrimonious (adj.)

1712, "sharp and bitter to the taste," formed irregularly (perhaps by influence of acrimonious) from Latin acer (fem. acris) "sharp to the senses, pungent, bitter; eager, fierce," also figuratively, of qualities, "active, ardent, spirited," also "hasty, quick, passionate;" of mind "violent, vehement; subtle, penetrating," from PIE *akri- "sharp," from root *ak- "be sharp, rise (out) to a point, pierce." Of feelings, temper, etc., in English from 1781. The -id suffix probably is in imitation of acid. Acrious (1670s) is a correct formation, but seldom seen. Related: Acridly.

📘单词丨acrid (adj.)

"quality of being acrid," 1799, from acrid + -ity. Acridness (1759) is older.

📘单词丨acridity (n.)

"number of acres in a tract of land," 1795, from acre + -age.

📘单词丨acreage (n.)

Old English æcer "tilled field, open land," from Proto-Germanic *akraz "field, pasture" (source also of Old Norse akr, Old Saxon akkar, Old Frisian ekker, Middle Dutch acker, Dutch akker, Old High German achar, German acker, Gothic akrs "field"), from PIE root *agro- "field."
"[O]riginally 'open country, untenanted land, forest'; ... then, with advance in the agricultural state, pasture land, tilled land, an enclosed or defined piece of land" [OED]. In English at first without reference to dimension; in late Old English the amount of land a yoke of oxen could plow in a day, afterward defined by statute 13c. and later as a piece 40 poles by 4, or an equivalent shape [OED cites 5 Edw. I, 31 Edw. III, 24 Hen. VIII]. The older sense is retained in God's acre "churchyard."
The Germanic word was adopted early in Old French and Medieval Latin, hence the Modern English spelling, which by normal development would be *aker (compare baker from Old English bæcere).

📘单词丨acre (n.)

"legal settlement" of a debt, obligation, etc., early 14c., aquitaunce, from Old French aquitance and Medieval Latin acquietantia; see acquit + -ance.

📘单词丨acquittance (n.)

early 15c., aquitaille, "payment of debt or retribution;" see acquit + -al (2). Sense of "a release from debt or obligation" is from mid-15c.; that of "freeing from charge or offense" (by legal process) is from 1530s.

📘单词丨acquittal (n.)

"freed, exonerated," 1670s, past-participle adjective from acquit (v.). Formerly in this sense was acquit (late 14c.).

📘单词丨acquitted (adj.)

mid-13c., aquiten, "repay, reciprocate, reward or retaliate for" (a good or bad deed); c. 1300 as "satisfy a debt; redeem (a pledge)," from Old French aquiter, acquiter "pay, pay up, settle a claim" (12c., Modern French acquitter), from a- "to" (see ad-) + quite "free, clear," from Medieval Latin quitus, quittus, from Latin quietus "free" (in Medieval Latin "free from war, debts, etc."), also "calm, resting" (from PIE root *kweie- "to rest, be quiet"). Also in part from Medieval Latin acquitare.
From mid-14c. as "relieve (someone) of an obligation, release from a pledge," hence the meanings "set (an accused person) free from charges, pronounce not guilty," and "discharge one's duty; behave or conduct oneself" (for better or worse), all of which date to late 14c. The notion in the word is "to release or discharge," from an obligation or from accusation, guilt, censure, or suspicion. Related: Acquitted; acquitting.

📘单词丨acquit (v.)

1630s, "owned through acquisition" (now obsolete, this sense going with acquired), from Latin acquisit-, past-participle stem of acquirere "accumulate, gain" (see acquire) + -ive. Meaning "given to acquisition, avaricious" is by 1824. Related: Acquisitively (1590s); acquisitiveness.

📘单词丨acquisitive (adj.)

late 14c., adquisicioun, "act of obtaining," from Old French acquisicion "purchase, acquirement" (13c., Modern French acquisition) or directly from Latin acquisitionem (nominative acquisitio), noun of action from past-participle stem of acquirere "get in addition, accumulate," from ad "to," here perhaps emphatic (see ad-), + quaerere "to seek to obtain" (see query (v.)).
The meaning "thing obtained" is from late 15c. The vowel change of -ae- to -i- in Latin is due to a phonetic rule in that language involving unaccented syllables in compounds.

📘单词丨acquisition (n.)

"act of acquiring; that which is acquired," 1620s, from acquire + -ment. Perhaps modeled on French acquerement (16c.).

📘单词丨acquirement (n.)

c. 1600, "gained by effort," past-participle adjective from acquire. Of diseases, "occurring after birth, thus not dependent on heredity," 1842 (opposed to congenital); acquired immune deficiency is attested by 1980; acquired immune deficiency syndrome by 1982. Acquired taste is attested from 1734.

📘单词丨acquired (adj.)

"to get or gain, obtain," mid-15c., acqueren, from Old French aquerre "acquire, gain, earn, procure" (12c., Modern French acquérir), from Vulgar Latin *acquaerere, corresponding to Latin acquirere/adquirere "to get in addition to, accumulate, gain," from ad "to," here perhaps emphatic (see ad-), + quaerere "to seek to obtain" (see query (v.)). Reborrowed in current form from Latin c. 1600. Related: Acquired; acquiring.

📘单词丨acquire (v.)

1630s, "rest, quiet, satisfaction," from French acquiescence, noun of action from acquiescer "to yield or agree to; be at rest" (see acquiesce). Meaning "silent consent, passive assent" is recorded from 1640s.

📘单词丨acquiescence (n.)
