American English vocabulary

The United States has given the English lexicon thousands of words, meanings, and phrases. Several thousand are now used in English as spoken internationally. Some words are only used within North American English and American English.
Creation of an American lexicon.
The process of coining new lexical items started as soon as the colonists began borrowing names for unfamiliar flora, fauna, and topography from the Native American languages. Examples of such names are "opossum, raccoon, squash" and "moose" (from Algonquian). Other Native American loanwords, such as "wigwam" or "moccasin", describe articles in common use among Native Americans. The languages of the other colonizing nations also added to the American vocabulary; for instance, "cookie", "cruller", "stoop", and "pit" (of a fruit) from Dutch; "angst, kindergarten, sauerkraut" from German, "levee, portage" ("carrying of boats or goods") and (probably) "gopher" from French; "barbecue, stevedore, and rodeo" from Spanish.
Among the earliest and most notable regular "English" additions to the American vocabulary, dating from the early days of colonization through the early 19th century, are terms describing the features of the North American landscape; for instance, "run, branch, fork, snag, bluff, gulch, neck" (of the woods), "barrens, bottomland, notch, knob, riffle, rapids, watergap, cutoff, trail, timberline" and "divide." Already existing words such as "creek, slough, sleet" and (in later use) "watershed" received new meanings that were unknown in England.
Other noteworthy American toponyms are found among loanwords; for example, "prairie, butte" (French); "bayou" (Choctaw via Louisiana French); "coulee" (Canadian French, but used also in Louisiana with a different meaning); "canyon, mesa, arroyo" (Spanish); "vlei, skate, kill" (Dutch, Hudson Valley).
The word "corn", used in England to refer to wheat (or any cereal), came to denote the plant "Zea mays", the most important crop in the U.S., originally named "Indian corn" by the earliest settlers; wheat, rye, barley, oats, etc. came to be collectively referred to as "grain". Other notable farm related vocabulary additions were the new meanings assumed by "barn" (not only a building for hay and grain storage, but also for housing livestock) and "team" (not just the horses, but also the vehicle along with them), as well as, in various periods, the terms "range, (corn) crib, truck, elevator, sharecropping" and "feedlot."
"Ranch," later applied to a house style, derives from Mexican Spanish; most Spanish contributions came after the War of 1812, with the opening of the West. Among these are, other than toponyms, "chaps" (from "chaparreras), plaza, lasso, bronco, , rodeo;" examples of "English" additions from the cowboy era are "bad man, maverick, chuck" ("food") and "Boot Hill;" from the California Gold Rush came such idioms as "hit pay dirt" or "strike it rich." The word "blizzard" probably originated in the West. A couple of notable late 18th century additions are the verb "belittle" and the noun "bid," both first used in writing by Thomas Jefferson.
With the new continent developed new forms of dwelling, and hence a large inventory of words designating real estate concepts "(land office, lot, outlands, waterfront," the verbs "locate" and "relocate, betterment, addition, subdivision)," types of property "(log cabin, adobe" in the 18th century; "frame house, apartment, tenement house, shack, " in the 19th century; "project, condominium, townhouse, split-level, mobile home, multi-family" in the 20th century), and parts thereof "(driveway, breezeway, backyard, dooryard; clapboard, siding, trim, baseboard; stoop" (from Dutch), "family room, den;" and, in recent years, "HVAC, central air, walkout basement)."
Ever since the American Revolution, a great number of terms connected with the U.S. political institutions have entered the language; examples are "run (i.e, for office), gubernatorial, primary election, carpetbagger" (after the Civil War), "repeater", "lame duck" (a British term used originally in Banking) and "pork barrel." Some of these are internationally used (for example, "caucus, gerrymander, filibuster, exit poll)."
19th century onwards.
The development of material innovations during the Industrial Revolution throughout the 19th and 20th centuries was the source of a massive stock of distinctive new concepts, with their accompanying new words, phrases and idioms. Typical examples are the vocabulary of "railroading" (see further at rail terminology) and "transportation" terminology, ranging from names of roads (from "dirt roads" and "back roads" to "freeways" and "parkways)" to road infrastructure "(parking lot, overpass, rest area)," and from automotive terminology to "public transit" (for example, in the sentence ""riding" the "subway downtown""); such American introductions as "commuter" (from "commutation ticket), concourse, to board" (a vehicle), "to park, double-park" and "parallel park" (a car), "" or the noun "terminal" have long been used in all dialects of English.
Trades of various kinds have endowed (American) English with household words describing jobs and occupations "(bartender, longshoreman, patrolman, hobo, bouncer, bellhop, roustabout, white collar, blue collar, employee, boss" [from Dutch], "intern, busboy, mortician, senior citizen)," businesses and workplaces "(department store, supermarket, thrift store, gift shop, drugstore, motel, main street, gas station, hardware store, savings and loan, hock" [also from Dutch]), as well as general concepts and innovations "(automated teller machine, smart card, cash register, dishwasher, reservation" [as at hotels], "pay envelope, movie, mileage, shortage, outage, blood bank)."
Already existing English words—such as "store, shop, dry goods, haberdashery, lumber"—underwent shifts in meaning; some—such as "mason, student, clerk", the verbs "can" (as in "canned goods"), "ship, fix, carry, enroll" (as in school), "run" (as in "run a business"), "release" and "haul"—were given new significations, while others (such as "tradesman)" have retained meanings that disappeared in England. From the world of business and finance came "break-even, merger, , downsize, disintermediation, bottom line;" from sports terminology came, jargon aside, "Monday-morning quarterback, cheap shot, game plan" (football); "in the ballpark, out of left field, off base, hit and run," and many other idioms from baseball; gamblers coined "bluff, , ante, bottom dollar, raw deal, pass the buck, ace in the hole, freeze-out, showdown;" miners coined "bedrock, bonanza, peter out, pan out" and the verb "prospect" from the noun; and railroadmen are to be credited with "make the grade, sidetrack, head-on," and the verb "railroad." A number of Americanisms describing material innovations remained largely confined to North America: "elevator, ground, gasoline;" many automotive terms fall in this category, although many do not "(hatchback, sport utility vehicle, station wagon, tailgate, motorhome, truck, pickup truck, to exhaust)."
In addition to the above-mentioned loans from French, Spanish, Mexican Spanish, Dutch, and Native American languages, other accretions from foreign languages came with 19th and early 20th century immigration; notably, from Yiddish "(chutzpah, schmooze, tush") and German—"hamburger" and culinary terms like "frankfurter/franks, liverwurst, sauerkraut, wiener, deli(catessen); scram, kindergarten, gesundheit;" musical terminology "(whole note, half note," etc.); and apparently "cookbook, fresh" ("impudent") and "what gives?" Such constructions as "Are you coming with?" and "I like to dance" (for "I like dancing") may also be the result of German or Yiddish influence.
Finally, a large number of English colloquialisms from various periods are American in origin; some have lost their American flavor (from "OK" and "cool" to "nerd" and "24/7)," while others have not "(have a nice day, for sure);" many are now distinctly old-fashioned "(swell, groovy)." Some English words now in general use, such as "hijacking, disc jockey, boost, bulldoze" and "jazz," originated as American slang. Among the many English idioms of U.S. origin are "get the hang of, bark up the wrong tree, keep tabs, run scared, take a backseat, have an edge over, stake a claim, take a shine to, in on the ground floor, bite off more than one can chew, off/on the wagon, stay put, inside track, stiff upper lip, bad hair day, throw a monkey wrench/monkeywrenching, under the weather, jump bail, come clean, come again?, it ain't over till it's over," and "what goes around comes around."
Morphology.
American English has always shown a marked tendency to use nouns as verbs. Examples of verbed nouns are "interview, advocate, vacuum, lobby, pressure, rear-end, transition, feature, profile, spearhead, skyrocket, showcase, service" (as a car), "corner, torch, exit" (as in "exit the lobby"), "factor" (in mathematics), "gun" ("shoot"), "author" (which disappeared in English around 1630 and was revived in the U.S. three centuries later) and, out of American material, "proposition, graft" (bribery), "bad-mouth, vacation, major, backpack, backtrack, intern, ticket" (traffic violations), "hassle, blacktop, peer-review, dope" and "OD", and, of course "verbed" as used at the start of this sentence.
Compounds coined in the U.S. are for instance "foothill, flatlands, badlands, landslide" (in all senses), "overview" (the noun), ", teenager, brainstorm, , hitchhike, smalltime, , frontman, lowbrow" and "highbrow, hell-bent, foolproof, nitpick, about-face" (later verbed), "upfront" (in all senses), "fixer-upper, no-show;" many of these are phrases used as adverbs or (often) hyphenated attributive adjectives: "non-profit, for-profit, free-for-all, ready-to-wear, catchall, low-down, down-and-out, down and dirty, in-your-face, nip and tuck;" many compound nouns and adjectives are open: "happy hour, fall guy, capital gain, road trip, wheat pit, head start, plea bargain;" some of these are colorful "(empty nester, loan shark, , buzz saw, ghetto blaster, dust bunny)," others are euphemistic "(differently abled (physically challenged), human resources, affirmative action, correctional facility)."
Many compound nouns have the form verb plus preposition: ", stopover, lineup, , tryout, spin-off, rundown" ("summary"), "shootout, holdup, hideout, comeback, cookout, kickback, makeover, takeover, rollback" ("decrease"), "rip-off, come-on, shoo-in, fix-up, tie-in, tie-up" ("stoppage"), "stand-in." These essentially are nouned phrasal verbs; some prepositional and phrasal verbs are in fact of American origin "(spell out, figure out, hold up, brace up, size up, rope in, back up/off/down/out, step down, miss out, kick around, cash in, rain out, check in" and "check out" (in all senses), "fill in" ("inform"), "kick in" or "throw in" ("contribute"), "square off, sock in, sock away, factor in/out, come down with, give up on, lay off" (from employment), "run into" and "across" ("meet"), "stop by, pass up, put up" (money), "set up" ("frame"), "trade in, pick up on, pick up after, lose out)."
Noun endings such as "-ee (retiree), -ery (bakery), -ster (gangster)" and "-cian (beautician)" are also particularly productive. Some verbs ending in "-ize" are of U.S. origin; for example, "fetishize, prioritize, burglarize, accessorize, itemize, editorialize, customize, notarize, weatherize, winterize, Mirandize;" and so are some back-formations "(locate, fine-tune, evolute, curate, donate, emote, upholster, peeve" and "enthuse)." Among syntactical constructions that arose in the U.S. are "as of" (with dates and times), "outside of, headed for, meet up with, back of, convince someone to, not about to" and "lack for."
Americanisms formed by alteration of some existing words include notably "pesky, phony, rambunctious, pry" (as in "pry open", from "prize), putter" (verb), "buddy, sundae, skeeter, sashay" and "kitty-corner." Adjectives that arose in the U.S. are for example, "lengthy, bossy, cute" and "cutesy, grounded" (of a child), "punk" (in all senses), "sticky" (of the weather), "through" (as in "through train", or meaning "finished"), and many colloquial forms such as "peppy" or "wacky". American blends include "motel, guesstimate, infomercial" and "televangelist." 
English words that survived in the United States and not in the United Kingdom.
A number of words and meanings that originated in Middle English or Early Modern English and that have been in everyday use in the United States dropped out in most varieties of British English; some of these have cognates in Lowland Scots. Terms such as "fall" ("autumn"), "faucet" ("tap"), "diaper" ("nappy"), "candy" ("sweets"), "skillet", "eyeglasses" and "obligate" are often regarded as Americanisms. "Fall" for example came to denote the season in 16th century England, a contraction of Middle English expressions like "fall of the leaf" and "fall of the year".
During the 17th century, English immigration to the British colonies in North America was at its peak and the new settlers took the English language with them. While the term "fall" gradually became obsolete in Britain, it became the more common term in North America. "Gotten" (past participle of "get") is often considered to be an Americanism, although there are some areas of Britain, such as Lancashire and North East England, that still continue to use it and sometimes also use "putten" as the past participle for "put" (which is not done by most speakers of American English).
Other words and meanings, to various extents, were brought back to Britain, especially in the second half of the 20th century; these include "hire" ("to employ"), "quit" ("to stop", which spawned "quitter" in the U.S.), "I guess" (famously criticized by H. W. Fowler), "baggage", "hit" (a place), and the adverbs "overly" and "presently" ("currently"). Some of these, for example "monkey wrench" and "wastebasket", originated in 19th century Britain.
The mandative subjunctive (as in "the City Attorney suggested that the case "not be closed"") is livelier in American English than it is in British English. It appears in some areas as a spoken usage and is considered obligatory in contexts that are more formal. The adjectives "mad" meaning "angry", "smart" meaning "intelligent", and "sick" meaning "ill" are also more frequent in American (these meanings are also frequent in Hiberno-English) than British English.
Regionally distinct vocabulary within the United States.
Linguist Bert Vaux created a survey, completed in 2003, polling English speakers across the United States about the specific words they would use in everyday speech for various concepts. This 2003 study concluded that:
