"overwhelm or confound with sudden surprise or wonder," 1580s, back-formation from Middle English amased "stunned, dazed, bewildered," (late 14c.), earlier "stupefied, irrational, foolish" (c. 1200), from Old English amasod, from a- (1), probably used here as an intensive prefix, + *mæs (see maze).

Amazon (n.)
late 14c., via Old French (13c.) or Latin, from Greek Amazon (mostly in plural Amazones) "one of a race of female warriors in Scythia," probably from an unknown non-Indo-European word, or possibly from an Iranian compound *ha-maz-an- "(one) fighting together" [Watkins], but in folk etymology long derived from a- "without" + mazos, variant of mastos "breast;" hence the story that the Amazons cut or burned off one breast so they could draw bowstrings more efficiently. Also used generally in early Modern English of female warriors; strong, tall, or masculine women; and the queen in chess.

The river in South America (originally called by the Spanish Rio Santa Maria de la Mar Dulce) rechristened by Francisco de Orellana, 1541, after an encounter with female warriors of the Tapuyas (or, as some say, beardless, long-haired male tribesmen). Others hold that the river name is a corruption of a native word in Tupi or Guarani meaning "wave").
Amazonian (adj.)
"bold, warlike," generally of women, 1590s, from Amazon + -ian. From 1847 in reference to the River Amazon.
ambage (n.)
late 14c., "winding or roundabout way, especially in speaking," usually plural, from Old French ambages, from Latin ambages "circumlocutions" (see ambagious).
ambagious (adj.)
"winding, devious, circuitous," 1650s, from French ambagieux, from Latin ambagiosus, from ambages "circuits, avoidings, circumlocutions," from amb- "around" (from PIE root *ambhi- "around") + agere "to set in motion, drive; to do, perform; keep in movement" (from PIE root *ag- "to drive, draw out or forth, move").
ambassador (n.)
late 14c., also embassador, "diplomatic emissary of a ruler in the court of another," from Old French embassator, ambassateor, which comes via Provençal or Old Spanish from Latin ambactus "a servant, vassal," from Celtic amb(i)actos "a messenger, servant," from PIE root *ambhi- "around" + *ag- "to drive, draw out or forth, move."

Compare embassy. Forms in am- and em- were used indiscriminately in English 17c.-18c. Until 1893 the United States sent and received none, having only ministers (often called ambassadors), who represented the state, not the sovereign.
ambassadorial (adj.)
1759, from ambassador + -al (1).
amber (n.)
mid-14c., ambre grice "ambergris; perfume made from ambergris," from the phrase in Old French (13c.) and Medieval Latin, from Arabic 'anbar "ambergris, morbid secretion of sperm-whale intestines used in perfumes and cookery" (see ambergris), which was introduced in the West at the time of the Crusades. Arabic -nb- often is pronounced "-mb-."

In Europe, amber was extended to fossil resins from the Baltic (late 13c. in Anglo-Latin; c. 1400 in English), and this has become the main sense as the use of ambergris has waned. Perhaps the perceived connection is that both were found washed up on seashores. Or perhaps it is a different word entirely, of unknown origin. Formerly they were distinguished as white or yellow amber for the Baltic fossil resin and ambergris "gray amber;" French distinguished the two substances as ambre gris and amber jaune.

Remarkable for its static electricity properties, Baltic amber was known to the Romans as electrum (compare electric). Amber as an adjective in English is from c. 1500; as a color name 1735. In the Old Testament it translates Hebrew chashmal, a shining metal.
ambergris (n.)
early 15c., from Old French ambre gris "gray amber," "a wax-like substance of ashy colour, found floating in tropical seas, a morbid secretion from the intestines of the sperm-whale. Used in perfumery, and formerly in cookery" [OED], via Medieval Latin from Arabic 'anbar (see amber). Its origin was known to Constantinus Africanus (obit c. 1087) bit it was a mystery in Johnson's day, and he records nine different theories; "What sort of thing is Ambergrease?" was a type of a puzzling question beyond conjecture. King Charles II's favorite dish was said to be eggs and ambergris [Macauley, "History of England"].
Praise is like ambergris; a little whiff of it, by snatches, is very agreeable; but when a man holds a whole lump of it to his nose, it is a stink and strikes you down. [Pope, c. 1720]
French gris is from Frankish *gris or some other Germanic source (cognates: Dutch grijs, Old High German gris; see gray (adj.)).
ambi-
word-forming element meaning "both, on both sides," from Latin ambi- "around, round about" (before vowels amb-, also sometimes reduced to am-, an-), from PIE root *ambhi- "around," which is probably an ablative plural (*ant-bhi "from both sides") of *ant- "front, forehead."
ambiance (n.)
1923, a reborrowing of the French form of ambience (q.v.), used in art writing as a term meaning "atmospheric effect of an arrangement."

ambidextrous (adj.)
also ambidexterous, "able to use both hands equally," 1640s, with -ous + Medieval Latin ambidexter, literally "right-handed on both sides," from ambi- "both, on both sides" (see ambi-) + dexter "right-handed" (see dexterity). An earlier English use of ambidexter (adj.) meant "double-dealer, one who takes both sides in a conflict" (late 14c.).

Its opposite, ambilevous "left-handed on both sides," hence "clumsy" (1640s) is rare. Ambidexter as a noun is attested from 1530s (in the sense "one who takes bribes from both sides") and is the earliest form of the word in English; its sense of "one who uses both hands equally well" appears by 1590s.
Ambien
trade name for prescription medication Zolpidem, which is used to treat insomnia, registered 1993 in U.S., no doubt suggested by ambient or words like it in French.

The notion of "going all around" led to the sense of "encircling, lying all around." Compare ambiance.
ambient (adj.)
1590s, "surrounding, encircling," from Latin ambientem (nominative ambiens) "a going around," present participle of ambire "to go around, go about," from amb- "around" (from PIE root *ambhi- "around") + ire "go" (from PIE root *ei- "to go").

ambisexual (adj.)
"unisex" (of clothing), also "bisexual," 1912 in the jargon of psychology, from ambi- + sexual. Ambosexous (1650s) and ambosexual (1935) both were used in the sense "hermaphrodite." Ambisextrous is recorded from 1929 as a humorous coinage based on ambidextrous.

Rarely used in English or Latin the literal sense. In early use in English always pejorative, of inordinate or overreaching desire; ambition was grouped with pride and vainglory, and sometimes meant little more than "arrogance." Neutral or positive senses are modern. Meaning "object of strong desire" is from c. 1600.

"simultaneous conflicting feelings," 1924 (1912 as ambivalency), from German Ambivalenz, coined 1910 by Swiss psychologist Eugen Bleuler (1857-1939) on model of German Equivalenz "equivalence," etc., from Latin ambi- "both, on both sides" (see ambi-) + valentia "strength," abstract noun from present participle of valere "be strong" (from PIE root *wal- "to be strong").

early 14c., from Old French ambler, of a horse or other quadruped, "go at a steady, easy pace" (12c.), from Latin ambulare "to walk, to go about, take a walk," perhaps a compound of ambi- "around" (from PIE root *ambhi- "around") and -ulare, from PIE root *el- "to go" (source also of Greek ale "wandering," alaomai "wander about;" Latvian aluot "go around or astray").

type of photograph on glass with lights given by silver and shades by a dark background showing through, 1855, American English, apparently from Greek ambrotos "immortal, imperishable" (see ambrosia), with second element from daguerreotype.
This invention consists in an improved process of taking photographic pictures upon glass, and also of beautifying and preserving the same, which process I have styled "ambrotype." My improved process has reference to the art of taking pictures photographically on a film of collodion upon the surface of a sheet of glass, the collodion being suitably prepared for the purpose. By the use of the said process, the beauty and permanency of such pictures are greatly increased, and I have on this account styled the process "ambrotype," from the Greek word ambrotos, immortal. ["Specification of the Patent granted to James A. Cutting, of Boston, in the United States of America, Photographer, for an Improved Process of taking Photographic Pictures upon Glass and also of Beautifying and Preserving the same. Dated London, July 26, 1854," printed in "Journal of the Franklin Institute," September 1855]

1798, "mobile or field hospital," from French ambulance, formerly (hôpital) ambulant (17c.), literally "walking (hospital)," from Latin ambulantem (nominative ambulans), present participle of ambulare "to walk, go about" (see amble).
AMBULANCE, s. f. a moveable hospital. These were houses constructed in a manner so as to be taken to pieces, and carried from place to place, according to the movements of the army; and served as receptacles in which the sick and wounded men might be received and attended. ["Lexicographica-Neologica Gallica" (The Neological French Dictionary), William Dupré, London, 1801]
The word was not common in English until the meaning transferred from "field hospital" to "vehicle for conveying wounded from the field" (1854) during the Crimean War. Extended early 20c. to vehicles to transport the sick or wounded in civilian life. In late 19c. U.S. the same word was used dialectally to mean "prairie wagon." Ambulance-chaser as a contemptuous term for a type of lawyer dates from 1897.

Middle English had ambulary "movable" (mid-15c.). Related: Ambulatorial.
ambulatory (n.)
"part of a building intended for walking," 1620s, from Medieval Latin ambulatorium, from Latin ambulatorius "movable, of or pertaining to a walker," from ambulare "to walk, go about" (see amble (v.)).
ambuscade (n.)
1580s, "act of lying concealed for the purpose of attacking by surprise," essentially a variant form of ambush (q.v.), "now more formal as a military term" [OED]. It is a reborrowing of that French word after it had been Italianized: Ambuscade is from French embuscade (16c.), Gallicized from Italian imboscata, literally "a hiding in the bush," compounded from the same elements as Old French embuscher.

Sometimes in early use ambuscado, with a faux Spanish ending of the sort popular in 17c. As a verb, "attack from a concealed position," 1590s.
