American English has always shown a marked tendency to use substantives as verbs. Examples of verbed nouns are interview, advocate, vacuum, lobby, expense, room, pressure, rear-end, transition, feature, profile, buffalo, weasel, express (mail), belly-ache, spearhead, skyrocket, showcase, merchandise, 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.
Compounds coined in the U.S. are for instance foothill, flatlands, badlands, landslide (in all senses), overview (the noun), backdrop, teenager, brainstorm, bandwagon, hitchhike, smalltime, deadbeat, 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, ambulance chaser, buzz saw, ghetto blaster, dust bunny), others are euphemistic (differently abled, human resources, physically challenged, affirmative action, correctional facility).
Many compound nouns have the form verb plus preposition: add-on, stopover, lineup, shakedown, tryout, spinoff, 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 on, kick around, cash in, rain out, check in and check out (in all senses), fill in ("inform"), kick 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 to be about to and lack for.
Americanisms formed by alteration of 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
A number of words and meanings that originated in Middle English or Early Modern English and that always 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"), pavement (to mean "road surface", where in Britain, as in Philadelphia, it is the equivalent of "sidewalk"), faucet, diaper, candy, skillet, eyeglasses, crib (for a baby), obligate, and raise a child are often regarded as Americanisms. Gotten (past participle of get) is often considered to be an Americanism, although there are some areas of Britain, such as Lancashire and Yorkshire, that still continue to use it and sometimes also use putten as the past participle for put.
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 AmE 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 than British English.
Regional differences
While written AmE is standardized across the country, there are several recognizable variations in the spoken language, both in pronunciation and in vernacular vocabulary. General American is the name given to any American accent that is relatively free of noticeable regional influences.
After the Civil War, the settlement of the western territories by migrants from the Eastern U.S. led to dialect mixing and leveling, so that regional dialects are most strongly differentiated along the Eastern seaboard. The Connecticut River and Long Island Sound is usually regarded as the southern/western extent of New England speech, which has its roots in the speech of the Puritans from East Anglia who settled in the Massachusetts Bay Colony. The Potomac River generally divides a group of Northern coastal dialects from the beginning of the Coastal Southern dialect area; in between these two rivers several local variations exist, chief among them the one that prevails in and around New York City and northern New Jersey, which developed on a Dutch substratum after the British conquered New Amsterdam. The main features of Coastal Southern speech can be traced to the speech of the English from the West Country who settled in Virginia after leaving England at the time of the English Civil War, and to the African influences from the African Americans who were enslaved in the South.
Although no longer region-specific, African American Vernacular English, which remains prevalent among African Americans, has a close relationship to Southern varieties of AmE and has greatly influenced everyday speech of many Americans.
A distinctive speech pattern was also generated by the separation of Canada from the United States, centered on the Great Lakes region. This is the Inland North Dialect-the "standard Midwestern" speech that was the basis for General American in the mid-20th Century (although it has been recently modified by the northern cities vowel shift). Those not from this area frequently confuse it with the North Midland dialect treated below, referring to both collectively as "Midwestern." The so-called "Minnesota Nice" dialect is also prevalent in the upper Midwest, and is characterized by influences from the German and Scandinavian settlers of the region (yah for yes/ja in German, pronounced the same way).
In the interior, the situation is very different. West of the Appalachian Mountains begins the broad zone of what is generally called "Midland" speech. This is divided into two discrete subdivisions, the North Midland that begins north of the Ohio River valley area, and the South Midland speech; sometimes the former is designated simply "Midland" and the latter is reckoned as "Highland Southern." The North Midland speech continues to expand westward until it becomes the closely related Western dialect which contains Pacific Northwest English as well as the well-known California English, although in the immediate San Francisco area some older speakers do not possess the cot-caught merger and thus retain the distinction between words such as cot and caught which reflects a historical Mid-Atlantic heritage. Mormon and Mexican settlers in the West influenced the development of Utah English.
The South Midland or Highland Southern dialect follows the Ohio River in a generally southwesterly direction, moves across Arkansas and Oklahoma west of the Mississippi, and peters out in West Texas. It is a version of the Midland speech that has assimilated some coastal Southern forms (outsiders often mistakenly believe South Midland speech and coastal South speech to be the same).
The island state of Hawaii has a distinctive Hawaiian Pidgin.
Finally, dialect development in the United States has been notably influenced by the distinctive speech of such important cultural centers as Boston, Chicago, Philadelphia, Charleston, New Orleans, and Detroit, which imposed their marks on the surrounding area
